معنى كلمة dolphin بالعربية
what do dolphins eat
The dolphin is a marine animal
Dolphins are marine mammals
The dolphin is not a fish but
a marine mammal that lives in all the seas of the globe. He follows the schools
of fish for food.
His back is black and his
belly white. His skin is smooth and smooth, allowing him to swim at speeds of
up to 44 km / h. It measures from 1 to 4 meters and its weight goes from 70 kg
to 400 kg according to its origin.
Its bill is long and has 80 to
100 teeth all equal. He uses it to catch his prey, but it is not useful for
chewing his food. The walls of his stomach are responsible for grinding his
prey. The fin of its tail (caudal) is flat and horizontally, that of the back
is developed.
Curiously the dolphin can see
from top to bottom and behind him but does not see very well from the front. He
uses his cat that emits ultrasounds that send him the location of obstacles and
schools of fish.
It is a warm-blooded animal
and the thick layer of fat under its skin helps it to keep its temperature
between 35 and 36 degrees C. It is a very sociable animal that lives in a group
and spends its days hunting the fish and have fun swimming, pouncing and diving
into the water.
The dolphin chooses a new
partner each year and mating occurs from October to December. The gestation
lasts about 360 days. The baby is born in line first and he knows how to swim
already. The cub of the dolphin will be mature around the age of 5 to 6 years.
While the birth is taking
place, two other females protect the baby and the mother against the predators.
His main enemy is the orca even though he is from the same family.
Fishermen follow the dolphins
to detect schools of fish and make good fishing. The species most captured by
humans, is the bottlenose dolphin. It is used to make shows. This shortens his
life a lot.
A free-roaming dolphin has a
lifespan of at least 40 years, while the dolphins' life is only seven years.
Blower dolphins are marine
animals
The Dolphin Souffleur, also
called Grand Dauphin, is a marine mammal. It inhabits all the temperate seas of
the world, except for the cold seas of the Arctic and Antarctic.
It is so called because of the
nostril that it has above his head and that allows him to evacuate the moist
air accumulated in his lungs.
It is gray on the back and
white on the belly. It is about 3 meters long and weighs about 300 kg.
On his forehead he carries a
mass of fat that allows him to receive ultrasound.
This animal lives in a group
and likes the physical contact and has fun to rub the end of the fins with his
companions or to play and jump on the waves. He is a born acrobat.
It stands near the coast and
seldom goes out to sea.
Predators are killer whales
and sharks. When there is a danger, the females are placed in the center with
their young and the males surround them and try to make flee the enemy.
The blower is a swimming
champion, his speed is 35-40 km / hour. It can go down to 200-300m depth to
feed or to flee a predator. He can stay deep in the water without breathing for
10 minutes.
Bottlenose dolphins feed on
fish, squid and crustaceans occasionally.
After reproduction, gestation
takes 12 months and births occur in summer. The little one is a meter and he
will stay with his mother for 6 years. The baby is weaned after 18 months.
After weaning she will be able to mate again.
From birth, the mother brings
the baby to the surface to breathe. Other females help the mother in this
action and one of them keeps the cubs while the mums go on the hunt.
The sexual maturity of the
male is reached between 10 and 13 years, and that of the female between 6 and
12 years.
The life of a dolphin blower
has a duration of 40 years for the female, that of the male is 30 years
