Killer whale

Killer whales, also known as orcas, were relatively small whales that were vicious marine predators.

Description
Despite their relatively small sizes compared to other whales, killer whales were among the largest sea predatory mammals.

Killer whales used their echolocation by emitting high-pitched sound to detect objects and other creatures. This ability did not work if the whale's hearing were to be impaired or if its detecting area was under the effect of a silence spell.

Behavior
Orcas were vicious predators that attacked anything within their range of detection. However, they were not excessively hostile, usually only attacking when hungry or provoked.

They were also intelligent animals that could be communicated with.

Combat
The main weapons killer whales used in combat were their powerful bites, which they could use to hold down their prey until it drowned.

Ecology
Killer whales usually hunted fish, squids, and warm-blooded animals, such as seals and other whales. They were resourceful hunters that employed sophisticated hunting strategies such as breaking ice sheets to knock their occupants into freezing cold water. A pod of killer whales was capable of collaborating to bring down much larger prey.

Despite being aggressive hunters, killer whales had a caring family structure, fiercely defending their calves, and sometimes even other whales, against threats. They were also known to ally themselves with aquatic elves.

Orcas were also commonly found in the temperate latitudes of Karpri. Whales native to that planet were unusually calm and graceful, a trait which caused them to be heavily hunted by outsiders.
