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.
They were also intelligent animals that could be communicated with.
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.
Killer whales were typically known to hunt fish and squids, as well as several kinds of warm-blooded animals, including seals, other whales, porpoises, dolphins, walruses, and penguins. 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.
Beyond Toril, orcas were commonly found in the temperate latitudes of the planet Karpri. Whales native to that planet were unusually calm and graceful, a trait which caused them to be heavily hunted by outsiders.
