The sea is hot to the extinct North Atlantic whale

As the ocean warms, the supply of food is scarce, the North Atlantic whale is facing the risk of rapid decline in the number of individuals and even extinction.

In the new study published in Oceanography, 17 scientists from the US, Canada and Norway said that the number of North Atlantic whales has dropped from 482 individuals in 2010 to 411 today. Experts explain why ocean temperatures rose in 2010, causing a decrease in whale food supplies.

North Atlantic whales are predominantly eating Calanus finmarchicus , a small crustacean, in the Gulf of Maine off the US coast. As seawater heats up, this crustacean moves the habitat so that the whales have to move along, getting closer to shipping routes and areas of human activity.

The Guardian cited the study, saying: "The health of plain whales is not guaranteed and it takes more time to get food. This makes whales face more risks and billions. mortality also increased. "

Scientists say this is a sign that the animal has not been able to adapt to the changing environment. In addition, the rapid warming of seawater in the Gulf of Maine may become a common feature of other oceans in the future.

North Atlantic whales often breed off the states of Georgia and Florida, USA, in the winter before coming to feed in the Gulf of Maine, bordering Massachusetts, New Hampshire, Maine and Canada, in spring and season. summer.

Gentle and slow-moving, this whale easily becomes a hunting target, causing the number of individuals to have severely declined at the end of the 18th and early 19th centuries. Since 1935, hunting whales slippery is banned in the US.

In the past decade, the whale is one of the most endangered species in the world. At least 17 individual whales died in 2017 and none of them were born in 2018.
