dolphin:
is an aquatic mammal within the infraorder
Cetacea. Dolphin species belong to the families Delphinidae (the oceanic
dolphins), Platanistidae (the Indian river dolphins), Iniidae (the New World
river dolphins), Pontoporiidae (the brackish dolphins), and possibly extinct
Lipotidae (baiji or Chinese river dolphin). There are 40 extant species named
as dolphins.

Adaptive traits :
Environmental and behavioral
adaptation of dolphins:
Dolphin is found almost all over the world, as most species prefer to live in the warm waters of tropical regions, and others prefer to live in cold climates، Some, such as marine dolphins, prefer to be in deep waters far from the coast.This type of dolphin has larger bodies than coastal dolphins, which have the ability to store heat and stay warm، This, in turn, helped it withstand the cold in the depths of the oceans, and it also uses its large size to defend itself and stay safe if it is exposed to predators، Dolphins also live in groups of up to 1,000 dolphins, although they may be aggressive towards each other, and often prefer places with a high abundance of food، It feeds mainly on fish
and squid, while others feed on other marine mammals.
Dolphin
has many adaptive qualities; The most important of them are the following:
Dolphin skin has adapted to cold
climates with a thick layer of fat, which also provides it with energy when
food is scarce.
Its limbs have adapted to fins
containing 4 finger-like appendages to guide its path, and it uses the dorsal
fin for balance, while the shape of the tail helps it push during swimming.
Some dolphins can slow their heart
rate to conserve oxygen, which helps them dive deep into the oceans. Dolphins' eyes are characterized by an
enlarged pupil, corneas and flat eyeballs due to the passage of abundant
amounts of light through their eyes, which enables them to see more clearly
what surrounds them. Dolphin Habitat
Dolphins can live in salt and fresh water.Which contributes to its distribution
between tropical and subarctic waters.It is found in all seas and oceans around
the world except the Aral Sea، And
the Caspian Sea.
It may also be found in many major
river systems in Asia and South America, where some coastal ocean dolphins
spend a reasonable time in fresh water, while common dolphins are distributed، Beaked dolphins are found in warm,
temperate s

Dolphin
reproduction :
Dolphins are characterized by several
characteristics, such as breathing air, warm blood, and carrying fetuses in the
wombs like other mammals.It gives birth to one fetus once from one to six
years, in addition to the possibility of giving birth to twins in rare cases.
As for the period of pregnancy, it
varies depending on the species.It may range between 9-17 months, and dolphins
feed their children by producing a thick dough such as milk after birth, and
breastfeed it to the child through the nipples.
Dolphin and the risk of
extinction :
Dolphins of all kinds are exposed to
a few marine enemies, but large dolphins such as orcas or so-called killer
whales usually attack other small dolphins, but this seems rare، On the other hand, dolphins in
general and river dolphins in particular, such as the Amazon River dolphin, the
Ganges River dolphin, and the Yangtze River dolphin, may be exposed to other
threats,

including the following:
Exposure to a wide range of diseases
and parasites such as the whale virus, which often leaves hundreds of animals
of different species dead. Injuries or
deaths resulting from dolphins colliding with boats, or colliding with their
propellers.
Exposure to pesticides, heavy metals,
plastics, and other industrial and agricultural pollutants that do not
decompose quickly in the environment.
Dolphins are killed in some parts of the world, such as Taiji in Japan
and the Faroe Islands.Because it is a source of food, even though dolphin meat
is rich in mercury, and therefore may pose a threat to human health when
consumed. Various fishing methods, such
as the use of drift nets and gill nets, unintentionally kill many dolphins.In
1962, thousands of dolphins were killed sideways during a shark culling program
in Queensland، Which
killed approximately 50,000 sharks

Amazing
facts about dolphins:
They live in human-like societies and
share the evolution of the mind, and there is a link between brain size and the
social and cultural traits of marine mammals.
The study showed that dolphins live
just like humans in tightly knit social groups, cooperate with other species,
talk to each other and have regional dialects.
She added that dolphins participate
in hunting, and they also pass their skills to younger members, according to
the British newspaper The Telegraph.
The study showed that it is possible
to predict the brain size of intelligent marine mammals based on their social
and cultural structure.
The researchers concluded that
dolphins, with their cognition like humans, enable them to face the challenges
of social life.
Evolutionary biologist at the School
of Earth and Environmental Sciences at the University of Manchester, Susan
Schultz, stated that dolphins and whales have exceptionally large, anatomically
developed brains, thus creating a marine cultural environment similar to human
life.
Earlier, studies proved that dolphins
have a communication system that is unparalleled in living organisms, and
through this system dolphins are able to communicate with each other، So much so that scientists discovered
that dolphins greet each other and call each other by names like humans.
Dolphins also have a radar guidance
system similar to the sonar used by ships and submarines, to be able to
identify the danger surrounding them and to determine food locations.
Dolphins are characterized by ending
social creatures that live in groups of 10 to 12 individuals in order to
protect and provide food, as females and newborns remain in the group’s center
for protection، When
a member of this group gets sick or injured, do not leave him alone, but rather
stay with her until he dies.
