Blue whale or
blue whale
Blue whales are
the largest mammals in the world
The Blue Whale,
also called Blue Whale, is a mammalian animal of the order Cetacea.
It is the largest
mammal in the world. Its size is 30 meters in length and its weight of 170
tons. The female blue whale is bigger than the male.
He lives in all
the oceans of the globe where the water is cold.
It is a rather
lonely animal, but can be seen in groups when food is abundant in a specific
place.
His back is gray
blue and his belly is paler. He has on his back two small holes through which
he breathes.
For its diet, the
blue whale feeds on small shrimps, which it consumes from 2 to 4 tons per day.
His esophagus is so small that he can not eat bigger prey.
It plunges up to
200 meters deep and can remain underwater for 10 to 30 minutes.
Back to the
surface to breathe, he can project a water jet to more than 15 meters high.
Mating of blue
whales takes place during the winter and gestation lasts 10 to 12 months. After
reproduction, every 2-3 years, the female gives birth to a single cub that is
already 7 meters tall and weighs 2,000 kilos. The baby is fed on her mother's
milk at a rate of 200 to 400 liters a day.
The only predator
of the blue whale is the killer whale that attacks the smaller ones. Other
causes of death for fin whales are, for example, a collision with a ship, being
trapped in a fishing net, being trapped in an ice trap ...
There are 4 types
of fin whales, Blue Whales, Fin Whales, Humpback Whales and Minke Whales.
The life of a
blue whale for about 30 years.
Whales are
aquatic mammals
The whale looks
like a fish, but it is not a fish but a marine mammal. It's the biggest animal
in the world.
It can measure up
to 30 meters and weigh 150 tons. She lives in all the oceans of the world and
likes temperate waters as well as cold seas. It is a warm-blooded animal, it
breathes air and gives birth to a single little already formed!
Its size and
shape vary from one species to another. Its body ends with a caudal fin (tail)
horizontally unlike fish that have the tail vertically. His head is broad, his
small eyes are placed at the ends of his mouth and his nostrils (vents) are
placed towards the rear.
Like the human,
it has a 4-chamber heart, lungs, stomach, liver, kidneys and intestines. She
has no sense of smell, she has no ear flag, but has an inner ear like all other
mammals.
Toothed or baleen
whales feed on fish, squid, crustaceans and plankton.
The whale reaches
sexual maturity between 5 and 15 years of age. The female gives birth to a
small, calf, which develops at a surprising speed. The baby can grow 3-4
centimeters and weigh 80 kg more per day. It must be said that he drinks 72 to
90 kg of milk a day.
Humpback whales
Among the best
known of its kind are sperm whales, white whales, gray whales, blue whales,
right whales, humpback whales and beaked whales. Whaling has dramatically
decreased the population of many species.
The life of a
whale lasts from 60 to 90 years.
