Humpback whales hold the most moving record

That is the result of an American study proving that this mammal can perform a journey of more than 8,000 km to freeze.

The southern humpback whales move very far to escape the harsh winter. Crossing an average of 8,300 km, the humpback whales Megaptera Novaeangliae swam across the equator and raised their babies in the hot waters off Central America.

Dr. Kristin Rasmussen and colleagues of the Cascadia Research Collective Association in Olympia (USA) photographed a group of humpback whales off Costa Rica from June to October. These whales carry their own signs under the tail. allow to identify them.

As a result, researchers have identified some whales returning to Antarctica in the summer. Its mother and baby whale exceeded 8,400 km in 161 days. Another whale is observed in areas away from 8,640km. This is the farthest movement ever observed in marine mammals.

Gray whales also make long journeys between the Arctic and Mexico; Blue whales also move very far. However, no marine animal has ever broken the record held by whales.

The researchers explained that humpback whales find places with mild climates to feed their babies. When studying the temperature of the water where they traveled from Antarctica off the coast of Central America, they noted that this place always had a stable temperature from 21 to 28 ^o C.
