Today I will introduce to you the Arctic whale.
It is the only whalebone whale that inhabits near the Arctic Ocean.
The extreme length is 18 meters and weighs 60 tons.
They mostly feed on planktons.
They are very slow swimmers, and usually migrate alone or in small groups.
In modern times, the population has sharply dropped by whale fishing. It has become an endangered species.
Now, the whales are fished areas near Alaska and other.
I think that the whole world needs to prohibit trapping to stop the Arctic whale from exterminating.
