Why is it called a 'false' killer whale?

It was named for its skull's superficial resemblance to that of the orca (killer whale), though the false killer whale is actually more closely related to pilot whales and belongs to a different genus.

How long do false killer whales live?

They are long-lived; captive records show males reaching 57 years and females 62 years. A female named Jumbo at Japan's Shimoda Floating Aquarium lived in captivity for 36 years, from 1970 to 2006.

Can false killer whales interbreed with other dolphins?

Yes, they can hybridize with bottlenose dolphins, producing fertile hybrid offspring known as 'wholphins.'

False Killer Whaleオキゴンドウ

Pseudorca crassidensNT— Near Threatened

The false killer whale is a large, highly social member of the dolphin family, found in tropical and subtropical oceans worldwide. Despite its name, it is more closely related to pilot whales than to the orca, and it hunts cooperatively for fish, squid, and even other marine mammals during the day. Known for its longevity — some captive individuals have lived past 60 years — the species is also notable for occasionally hybridizing with bottlenose dolphins. The IUCN classifies it as Near Threatened, citing bycatch and small, fragmented populations in parts of its range.
