Fin whales, humpback whales and sperm whales have been found to have spindle neurons, whose function is not well understood, which is a type of brain cell known to exist only in certain other species of high intelligence: humans, other great apes, bottlenose dolphins and elephants.
Orcas (or killer whales) are large, powerful aquatic apex predators. There have been incidents where orcas were perceived to attack humans in the wild, but such attacks are less common than those by captive orcas.

[1] Other instances of exploding animals are defensive in nature or the result of human ...

The whales make groans, pops and belches typically at frequencies around 500 Hz. The purpose of the sounds is not known but may be a form of communication between whales within the same group.
