Pseudorca crassidens (False Killer Whale)

Synonyms: Orca destructor; Orca meridionalis; Phocaena crassidens; Pseudorca meridionalis
Language: Spanish

Wikipedia Abstract

The false killer whale (Pseudorca crassidens) is a cetacean, and the third-largest member of the oceanic dolphin family (Delphinidae). It lives in temperate and tropical waters throughout the world. As its name implies, the false killer whale shares characteristics, such as appearance, with the more widely known killer whale. Like the killer whale, the false killer whale attacks and kills other cetaceans, but the two species do not belong to the same genus.
