Dolphins are marine mammals that are closely related
to whales and porpoises. There are almost forty species of
dolphin in 17 genera. They vary in size from 1.2 m (4 ft) and
40 kg (90 lb) (Maui's dolphin), up to 9.5 m (30 ft) and
10 tonnes (9.8 LT; 11 ST) (the orca or killer whale). They are
found worldwide, mostly in the shallower seas of the continental
shelves, and are carnivores, mostly eating fish and squid. The
family Delphinidae is the largest in the Cetacean order, and
evolved relatively recently, about ten million years ago, during
the Miocene. Dolphins are among the most intelligent animals,
and their often friendly appearance and seemingly playful
attitude have made them popular in human culture.
The name is originally from Greek
was related to the Greek δελφύς
The animal's name can therefore be interpreted as meaning "a
'fish' with a womb".
The name was transmitted via the Latin delphinus
(the romanization of the later Greek δελφῖνος - delphinos),
which in Middle Latin became dolfinus and in Old French
daulphin, which reintroduced the ph into the word.
The term mereswine (that is, sea pork) has also
historically been used.
The word is used in a few different ways. It can mean:
- any member of the family Delphinidae (oceanic dolphins),
- any member of the families Delphinidae and
Platanistoidea (oceanic and river dolphins),
- any member of the suborder Odontoceti (toothed whales;
these include the above families and some others),
- and is used casually as a synonym for bottlenose
dolphin, the most common and familiar species of dolphin.
This article uses the second definition and does not describe
porpoises (suborder Odontoceti, family Phocoenidae). Orcas and
some closely related species belong to the Delphinidae family
and therefore qualify as dolphins, even though they are called
whales in common language. A group of dolphins is called a
"school" or a "pod". Male dolphins are called "bulls", females
"cows" and young dolphins are called "calves".

whale-bottlenose dolphin hybrid. The wolphin is a fertile
hybrid. Two wolphins currently live at the Sea Life Park in

in the wild.
Evolution and anatomy
Dolphins, along with whales and porpoises, are descendants of
terrestrial mammals, most likely of the Artiodactyl order. The
ancestors of the modern day dolphins entered the water roughly
50 million years ago, in the Eocene epoch.
Modern dolphin skeletons have two small, rod-shaped pelvic
bones thought to be vestigial hind limbs. In October 2006, an
unusual bottlenose dolphin was captured in Japan; it had small
fins on each side of its genital slit, which scientists believe
to be a more pronounced development of these vestigial hind
Dolphins have a streamlined fusiform body, adapted for fast
swimming. The tail fin, called the fluke, is used for
propulsion, while the pectoral fins together with the entire
tail section provide directional control. The dorsal fin, in
those species that have one, provides stability while swimming.
Though it varies by species, basic coloration patterns are
shades of grey, usually with a lighter underside, often with
lines and patches of different hue and contrast.
The head contains the melon, a round organ used for
echolocation. In many species, elongated jaws form a distinct
beak; species such as the bottlenose have a curved mouth which
looks like a fixed smile. Some species have up to 250 teeth.
Dolphins breathe through a blowhole on top of their head. The
trachea is anterior to the brain. The dolphin brain is large and
highly complex, and is different in structure from that of most
Unlike most mammals, dolphins do not have hair, except for a
few hairs around the tip of their rostrum which they lose
shortly before or after birth.
The only exception to this is the Boto river dolphin, which has
persistent small hairs on the rostrum.
Dolphins' reproductive organs are located on the underside of
the body. Males have two slits, one concealing the penis and one
further behind for the anus. The female has one genital slit,
housing the vagina and the anus. Two mammary slits are
positioned on either side of the female's genital slit.
A recent study at the U.S. National Marine Mammal Foundation
revealed that dolphins, like humans, develop a natural form of
type 2 diabetes, which may lead to a better understanding of the
disease and new treatments for both humans and dolphins.
Most dolphins have acute eyesight, both in and out of the
water, and they can hear frequencies ten times or more above the
upper limit of adult human hearing.
Though they have a small ear opening on each side of their head,
it is believed hearing underwater is also, if not exclusively,
done with the lower jaw, which conducts sound to the middle ear
via a fat-filled cavity in the lower jaw bone. Hearing is also
used for echolocation, which all dolphins have. Dolphin teeth
are believed to function as antennae to receive incoming sound
and to pinpoint the exact location of an object.
The dolphin's sense of touch is also well-developed, with free
nerve endings densely packed in the skin, especially around the
snout, pectoral fins and genital area. However, dolphins lack an
olfactory nerve and lobes, and thus are believed to have no
sense of smell.
They do have a sense of taste and show preferences for certain
kinds of fish. Since dolphins spend most of their time below the
surface, tasting the water could function like smelling, in that
substances in the water can signal the presence of objects that
are not in the dolphin’s mouth.
Though most dolphins do not have hair, they do have hair
follicles that may perform some sensory function.
The small hairs on the rostrum of the Boto river dolphin are
believed to function as a tactile sense possibly to compensate
for the Boto's poor eyesight.

Dolphins are often regarded as one of Earth's most
intelligent animals, though it is hard to say just how
intelligent. Comparing species' relative intelligence is
complicated by differences in sensory apparatus, response modes,
and nature of cognition. Furthermore, the difficulty and expense
of experimental work with large aquatic animals has so far
prevented some tests and limited sample size and rigor in
others. Compared to many other species, however, dolphin
behavior has been studied extensively, both in captivity and in
the wild. See cetacean intelligence for more details.
Dolphins are social, living in pods of up to a dozen
individuals. In places with a high abundance of food, pods can
merge temporarily, forming a superpod; such groupings may
exceed 1,000 dolphins. Individuals communicate using a variety
of clicks, whistles and other vocalizations. They make
ultrasonic sounds for echolocation. Membership in pods is not
rigid; interchange is common. However, dolphins can establish
strong social bonds; they will stay with injured or ill
individuals, even helping them to breathe by bringing them to
the surface if needed.
This altruism does not appear to be limited to their own species
however. The dolphin Moko in New Zealand has been
observed guiding a female Pygmy Sperm Whale together with her
calf out of shallow water where they had stranded several times.
They have also been seen protecting swimmers from sharks by
swimming circles around the swimmers
or charging the sharks to make them go away.
Dolphins also display culture, something long believed to be
unique to humans (and possibly other primate species). In May
2005, a discovery in Australia found Indo-Pacific bottlenose
dolphins (Tursiops aduncus) teaching their young to use
tools. They cover their snouts with sponges to protect them
while foraging. This knowledge is mostly transferred by mothers
to daughters, unlike simian primates, where knowledge is
generally passed on to both sexes. Using sponges as mouth
protection is a learned behavior.
Another learned behavior was discovered among river dolphins in
Brazil, where some male dolphins use weeds and sticks as part of
a sexual display.
Dolphins engage in acts of aggression towards each other. The
older a male dolphin is, the more likely his body is to be
covered with bite scars. Male dolphins engage in such acts of
aggression apparently for the same reasons as humans: disputes
between companions and competition for females. Acts of
aggression can become so intense that targeted dolphins
sometimes go into exile as a result of losing a fight.
Male bottlenose dolphins have been known to engage in
infanticide. Dolphins have also been known to kill porpoises for
reasons which are not fully understood, as porpoises generally
do not share the same diet as dolphins, and are therefore not
competitors for food supplies.
Reproduction and sexuality
Dolphin copulation happens belly to belly; though many
species engage in lengthy foreplay, the actual act is usually
brief, but may be repeated several times within a short time
span. The gestation period varies with species; for the small
Tucuxi dolphin, this period is around 11 to 12 months, while for
the orca, the gestation period is around 17 months. They usually
become sexually active at a young age, even before reaching
sexual maturity. The age of sexual maturity varies by species
Dolphins are known to have sex for reasons other than
needed], sometimes also engaging in homosexual
behavior. Various species sometimes engage in sexual behavior
including copulation with other dolphin species. Sexual
encounters may be violent, with male dolphins sometimes showing
aggressive behavior towards both females and other males.
Occasionally, dolphins behave sexually towards other animals,
Chinese White Dolphin
The adult dolphin is usually white or grey in colour.
The population along the Chinese coast is unique in that they
exhibit a pink-coloured skin.
This colour of the skin is not a result of colour pigmentation, but
is actually from blood vessels used for thermoregulation to prevent
overheating during exertion.
Chinese White Dolphin can live up to 40 years. The eldest dolphin
lives in Hong Kong and is known to be about 33 years old. Scientists
have discovered that the age of a dead dolphin can be determined by
observing the cross section of its teeth.
sea of Hong Kong is becoming a very dangerous habitat for the
Chinese White Dolphins. This is due to the increase in poaching,
landfills, and sea traffic. Since Chinese White Dolphins are
territorial animals and rarely stray far away from their habitat,
the water pollution in Hong Kong has a high
Various methods of feeding exist among and within species,
some apparently exclusive to a single population. Fish and squid
are the main food, but the false killer whale and the orca also
feed on other marine mammals.
One common feeding method is herding, where a pod squeezes a
school of fish into a small volume, known as a bait ball.
Individual members then take turns plowing through the ball,
feeding on the stunned fish. Coralling is a method where
dolphins chase fish into shallow water to more easily catch
them. In South Carolina, the Atlantic bottlenose dolphin takes
this further with "strand feeding", driving prey onto mud banks
for easy access.
In some places, orcas come to the beach to capture sea lions.
Some species also whack fish with their flukes, stunning them
and sometimes knocking them out of the water.
Reports of cooperative human-dolphin fishing date back to the
ancient Roman author and natural philosopher Pliny the Elder.
A modern human-dolphin partnership currently operates in Laguna,
Santa Catarina, Brazil. Here, dolphins drive fish towards
fishermen waiting along the shore and signal the men to cast
their nets. The dolphins’ reward is the fish that escape the
Dolphins are capable of making a broad range of sounds using
nasal airsacs located just below the blowhole. Roughly three
categories of sounds can be identified: frequency modulated
whistles, burst-pulsed sounds and clicks. Dolphins communicate
with their whistles and burst-pulsed sounds, though the nature
and extent of that ability is not known. At least some dolphin
species can identify themselves using a signature whistle.
The clicks are directional and are for echolocation, often
occurring in a short series called a click train. The click rate
increases when approaching an object of interest. Dolphin
echolocation clicks are amongst the loudest sounds made by
Dolphins occasionally leap above the water surface, and
sometimes perform acrobatic figures (for example, the spinner
dolphin). Scientists are not certain about the purpose's of the
acrobatics. Possibilities include locating schools of fish by
looking at above-water signs like feeding birds, communicating
with other dolphins, dislodging parasites or simple amusement.
Play is an important part of dolphin culture. Dolphins play
with seaweed and play-fight with other dolphins. At times they
harass other local creatures, like seabirds and turtles.
Dolphins enjoy riding waves and frequently surf coastal swells
and the bow waves of boats, at times “leaping” between the dual
bow waves of a moving catamaran. Occasionally, they playfully
interact with swimmers. Captive dolphins have been observed in
aquariums engaging in complex play behaviour which involves the
creation and manipulation of bubble rings.
Generally, dolphins sleep with only one brain hemisphere in
slow-wave sleep at a time, thus maintaining enough consciousness
to breathe and to watch for possible predators and other
threats. Earlier sleep stages can occur simultaneously in both
hemispheres. In captivity, dolphins seemingly enter a fully
asleep state where both eyes are closed and there is no response
to mild external stimuli. In this case respiration is automatic,
a tail kick reflex keeps the blowhole above the water if
necessary. Anesthetized dolphins initially show a tail kick
a similar state has been observed with wild Sperm Whales, it is
not known if dolphins in the wild reach this state.
The Indus river dolphin has a different sleep method from other
dolphin species. Living in water with strong currents and
potentially dangerous floating debris, it must swim continuously
to avoid injury. As a result, this species sleeps in very short
bursts which last between 4 and 60 seconds.
Except for humans (discussed below), dolphins have few
natural enemies. Some species or specific populations have none,
making them apex predators. For most of the smaller species of
dolphins, only a few of the larger sharks, such as the bull
shark, dusky shark, tiger shark and great white shark are a
potential risk, especially for calves. Some of the larger
dolphinic species, especially orcas (killer whales), may also
prey smaller dolphins, but this seems rare. Dolphins also suffer
from a wide variety of diseases and parasites.[citation
Some dolphin species face an uncertain future, especially
some river dolphin species such as the Amazon river dolphin, and
the Ganges and Yangtze river dolphin, which are critically or
seriously endangered. A 2006 survey found no individuals of the
Yangtze river dolphin, which now appears to be functionally
Pesticides, heavy metals, plastics, and other industrial and
agricultural pollutants that do not disintegrate rapidly in the
environment concentrate in predators such as dolphins.
Injuries or deaths due to collisions with boats, especially
their propellers, are also common.
Various fishing methods, most notably purse seine fishing for
tuna and the use of drift and gill nets, unintentionally kill
Accidental by-catch in gill nets and incidental captures in
antipredator nets that protect marine fish farms are common and
pose a risk for mainly local dolphin populations.
In some parts of the world, such as Taiji in Japan and the Faroe
Islands, dolphins are traditionally considered as food, and are
killed in harpoon or drive hunts.
Dolphin meat is high in mercury, and may thus pose a health
danger to humans when consumed.
Dolphin safe labels attempt to reassure consumers fish and
other marine products have been caught in a dolphin-friendly
way. The original deal with "Dolphin safe" labels was brokered
in the 1980s between marine activists and the major tuna
companies, and involved decreasing incidental dolphin kills by
up to 50% by changing the type of nets being used to catch the
tuna. It should be noted that the dolphins are only netted while
fishermen are in pursuit of smaller tuna. Albacore are not
netted this way, which makes albacore the only truly
Loud underwater noises, such as those resulting from naval
sonar use, live firing exercises, or certain offshore
construction projects, such as wind farms, may be harmful to
dolphins, increasing stress, damaging hearing, and causing
decompression sickness by forcing them to surface too quickly to
escape the noise.
Relationships with humans
Dolphins have long played a role in human culture. Dolphins
are common in Greek mythology and there are many coins from
ancient Greece which feature a man or boy or deity riding on the
back of a dolphin.
The Ancient Greeks welcomed dolphins; spotting dolphins riding
in a ship’s wake was considered a good omen.
In Hindu mythology, the Ganges River Dolphin is associated with
Ganga, the deity of the Ganges river.
In more recent times, the 1963 Flipper movie and the
subsequent 1964 television series, popularized dolphins
in Western society. The series, created by Ivan Tors, portrayed
a dolphin as a kind of seagoing Lassie. Flipper was a
Bottlenose Dolphin who understood commands and always behaved
heroically. Flipper was remade in 1996. In the 1990s
science fiction television series seaQuest DSV featured a
bottle-nose named Darwin who could communicate using a vocoder,
a fictional invention which translated clicks and whistles to
English and back. The 1993 movie Free Willy made a star
of the Orca playing Willy, Keiko. The 1977 horror movie Orca
paints a less friendly picture of the species. Here, a male Orca
takes revenge on fishermen after the killing of his mate. The
1973 movie The Day of the Dolphin portrayed kidnapped
dolphins performing a naval military assassination using
explosives. This was also explored in the similarly named
Simpsons Treehouse of Horror episode, Night of the Dolphin,
where Lisa frees a dolphin at a aquarium attraction and
unwittingly initiates their plan to overthrow the land-dwellers
and live in their place. In The Hitchhiker's Guide to the
Galaxy series, dolphins are the second most intelligent
species on Earth (after mice).
The renewed popularity of dolphins in the 1960s resulted in
the appearance of many dolphinaria around the world, making
dolphins accessible to the public. Criticism and animal welfare
laws forced many to close, although hundreds still exist around
the world. In the United States, the best known are the SeaWorld
marine mammal parks.
Organizations such as the Mote Marine Laboratory rescue and
rehabilitate sick, wounded, stranded or orphaned dolphins, while
others, such as the Whale and Dolphin Conservation Society and
Hong Kong Dolphin Conservation Society, work on dolphin
conservation and welfare. India has declared the Dolphin as
their national aquatic animal in an attempt to protect the
endangered Ganges River Dolphin. The Vikramshila Gangetic
Dolphin Sanctuary has been created in the Ganges river for the
protection of the animals.
Various scientists to have researched Dolphin behaviour have
proposed that their unusually high intelligence compared to
other animals means that dolphins should be seen as non-human
persons that should have their own specific rights, and that
it is morally unacceptable to keep them captive for
entertainment purposes, or to kill them; either intentionally
for consumption or as by-catch.
Although dolphins generally interact well with humans, some
attacks have occurred, most of them with small injuries.
The attacks can occur both in the wild and captivity.
Orcas, the largest species of dolphin, have been involved in
fatal attacks on humans in captivity. The record-holder of
documented orca fatal attacks is a male named Tilikum, that
belongs to SeaWorld and has played a role in the death of three
people in three different incidents (1991, 1999 and 2010).
There are documented incidents in the wild too, but none of them
Fatal attacks from other species are less common, but there
is a registered occurrence in the coast of Brazil in 1994, when
a man died after injuries suffered during a bottlenose dolphin
Non-fatal incidents occur more frequently, both in wild and
While dolphin attacks are much rarer than other sea animal
attacks, such as shark ones, some scientists are worried about
the careless programs of human-dolphin interaction. Dr. Andrew
J. Read, a biologist at the Duke University Marine Laboratory
who studies dolphin attacks, points that dolphins are large and
wild predators, so people should be more careful when interact
Dolphins are an increasingly popular choice of
animal-assisted therapy for psychological problems and
developmental disabilities. For example, a 2005 study found
dolphins an effective treatment for mild to moderate depression.
However, this study was criticized on several grounds. For
example, it is not known whether dolphins are more effective
than common pets.
Reviews of this and other published dolphin-assisted therapy
(DAT) studies have found important methodological flaws and have
concluded that there is no compelling scientific evidence that
DAT is a legitimate therapy or that it affords more than
fleeting mood improvement.
A number of militaries have employed dolphins for various
purposes from finding mines to rescuing lost or trapped humans.
The military use of dolphins, however, drew scrutiny during the
Vietnam War when rumors circulated that the United States Navy
was training dolphins to kill Vietnamese divers.
The United States Navy denies that at any point dolphins were
trained for combat. Dolphins are still being trained by the
United States Navy on other tasks as part of the U.S. Navy
Marine Mammal Program. The Russian military is believed to have
closed its marine mammal program in the early 1990s. In 2000 the
press reported that dolphins trained to kill by the Soviet Navy
had been sold to Iran.
Dolphins are also common in contemporary literature,
especially science fiction novels. Dolphins play a military role
in William Gibson's short story Johnny Mnemonic, in which
cyborg dolphins find submarines and decode encrypted
information. Dolphins play a role as sentient patrollers of the
sea enhanced with a deeper empathy toward humans in Anne
McCaffrey's The Dragonriders of Pern series. In the
Known Space universe of author Larry Niven, dolphins play a
significant role as fully recognised "legal entities". More
humorous is Douglas Adams’ The Hitchhiker's Guide to the
Galaxy series of picaresque novels, in which dolphins are
the second most intelligent creatures on Earth (after mice,
followed by humans) and try in vain to warn humans of Earth’s
impending destruction. Their story is told in So Long, and
Thanks for All the Fish. Much more serious is their major
role in David Brin's Uplift series. A talking Dolphin named
"Howard" helps Hagbard Celine and his submarine crew fight the
evil Illuminati in Robert Shea and Robert Anton Wilson's
Dolphins appear frequently in non-science fiction literature.
In the book The Music of Dolphins by author Karen Hesse,
dolphins raise a girl from the age of four until the coast guard
eventually discovers her. Fantasy author Ken Grimwood wrote
dolphins into his 1995 novel Into the Deep about a marine
biologist struggling to crack the code of dolphin intelligence,
including chapters written from a dolphinian viewpoint.
Dolphins are a popular artistic motif, dating back to ancient
times. Examples include the Triton Fountain by Bernini and
depictions of dolphins in the ruined Minoan palace at Knossos
and on Minoan pottery.
Dolphin meat is consumed in a small number of countries
world-wide, which include Japan
and Peru (where it is referred to as chancho marino, or
While Japan may be the best-known and most controversial
example, only a very small minority of the population has ever
Dolphin meat is dense and such a dark shade of red as to
appear black. Fat is located in a layer of blubber between the
meat and the skin. When dolphin meat is eaten in Japan, it is
often cut into thin strips and eaten raw as sashimi,
garnished with onion and either horseradish or grated garlic,
much as with sashimi of whale or horse meat (basashi).
When cooked, dolphin meat is cut into bite-size cubes and then
batter-fried or simmered in a miso sauce with vegetables.
Cooked dolphin meat has a flavor very similar to beef liver.
