The pygmy killer whale (Feresa attenuata) is a poorly known and rarely seen oceanic dolphin. [3] It is the only species in the genus Feresa.It derives its common name from sharing some physical characteristics with the orca, also known as the killer whale.
Although pilot whales are not known to have many predators, possible threats come from humans and killer whales. Both species eat primarily squid. [19] The whales make seasonal inshore and offshore movements in response to the dispersal of their prey. [3]
Kogiidae is a family comprising at least two extant species of Cetacea, the pygmy (Kogia breviceps) and dwarf (K. sima) sperm whales.As their common names suggest, they somewhat resemble sperm whales, with squared heads and small lower jaws, but are much smaller, with much shorter skulls and more notable dorsal fins than sperm whales.

Predators may include great white sharks [28] and killer whales. [29] Pygmy sperm whales and dwarf sperm whales are unique among cetaceans in using a form of "ink" to evade predation in a manner similar to squid.
Other possible predators include the killer whale, the false killer whale, the pygmy killer whale and the short-finned pilot whale. [16] They are susceptible to parasites , and are known to exhibit both external ones like barnacles and remoras , and internal ones, like nematodes , trematodes , cestodes and acanthocephalans .
Orcas, or “killer whales,” can grow up to 27 feet long and weigh as much as six tons. Known as the ocean’s top predator, they’re extremely intelligent, with their own languages of clicks ...
Experts from California Killer Whale Project identified the four predators as “Hopper’s Pod.” The pod is named after its matriarch, Hopper. “We have known Hopper since she was born in 1995!
The name "pilot whale" originated with an early theory that pods were "piloted" by a leader. Other common names include the "pothead whale" (after the bulbous melon), and "blackfish" (a catch-all term used to designate numerous species of small, dark-colored toothed whales, including the pygmy sperm whale and false killer whale).
