False killer whale

The false killer whale (Pseudorca crassidens) is a large oceanic dolphin found in tropical and temperate seas worldwide. It is a social predator known for strong bonds and occasional mass strandings.

Oceanic dolphins: Oceanic dolphins are cetaceans in the family Delphinidae, adapted to life in marine waters. The false killer whale belongs to this family despite its misleading common name.
Cooperative hunting: Cooperative hunting is the coordinated pursuit or capture of prey by multiple animals. Groups of false killer whales have been observed pursuing fish together.
Bycatch: Bycatch is the unintended capture of animals during fishing operations targeting other species. False killer whales can become entangled in fishing gear, especially longlines.
Hawaiian false killer whale: The Hawaiian false killer whale is a distinct population segment inhabiting waters around the Hawaiian Islands. Its small, resident population has received focused conservation attention.
Orca: The orca (Orcinus orca) is the largest dolphin species and a distinct member of Delphinidae. Similarities in skull shape and color inspired the false killer whale's common name.
Echolocation: Echolocation is the use of reflected sound to locate objects and navigate. This toothed whale uses clicks and returning echoes to sense underwater surroundings.
Longline fishing: Longline fishing uses a main line carrying many baited hooks to catch fish. Hooks and lines can injure or entangle false killer whales seeking fish.
Northwestern Hawaiian Islands mass stranding: A 2013 event in the Northwestern Hawaiian Islands stranded a group of false killer whales. The event illustrates the species' vulnerability to group strandings in remote waters.
Pseudorca crassidens: Pseudorca crassidens is the scientific name of the false killer whale, the sole living species in its genus. This binomial identifies the species precisely in taxonomic and research contexts.
Toothed whales: Toothed whales are cetaceans with teeth that use echolocation, including dolphins and sperm whales. Their sensory and feeding adaptations provide the broader context for this dolphin's biology.
