baleen whale

A head-on collision with a speeding ferry left a humpback whale with a deformed jaw and it died in agony within hours.

Two bowhead whales in the Arctic synchronize their dives, demonstrating the ability to communicate by sound over extremely long distances.

Australian scientists discovered that the ancestors of today's large and gentle blue whales were dangerous hunters who could catch and kill prey with sharp teeth.

In the natural world there are some creatures that possess strange teeth. Most notably a popular North American fish and a deep-sea squid species that develop human-like teeth.
