The whale


The whale is a marine mammal belonging to the large cetacean family, of which there are two categories: the mysticetes including the baleen whales, and the odontocetes grouping the toothed whales.

The whale is a mammal very imposing: it can measure up to 30 meters long. Its weight can go up to 150 tons. It also has a tongue that can weigh 2 tons and large teeth called baleen.

This mammal breathes with its lungs when swimming on the surface. Some whale species (such as the sperm whale) can snorkel up to 2 km deep and stay underwater for over an hour.
His place of life
The whale is a marine hope. It is therefore mainly found in the open sea and near the coast. Southern Right Whales, for example, are located in Antarctica but also in the Indian Ocean and the Pacific. They live in groups and frequently migrate from one ocean to another.

His diet
This huge marine mammal feeds simply on a tiny shrimp commonly called "Krill". But the whale also eats plankton in cold waters. This cetacean consumes on average 2 tons of food per day, or about 730 tons of krill and plankton each year.

His reproduction
The gestation period of a whale lasts an average of 6 months. The female can give birth to only one calf. Mating is belly to tummy, thanks to their fins that allow them to hold firmly.

His life expectancy
A whale can live from 65 to 80 years old. The animal is unfortunately endangered because of the different whale hunts practiced in the world.

Particular signs
While other cetaceans use echolocation to hunt, whales use this method very little.
