False Killer Whale

Fascinating facts about the False Killer Whale

• False killer whales can dive deeper, reaching a recorded 927.5 m (3,043 ft) in Hawaii. This extreme depth lets them hunt squid and fish in the dark mid-water zone where few predators go, expanding their food web role far below the sunlit surface. Their ability to stay down for up to 18.5 minutes shows a physiological adaptation for oxygen storage and pressure resistance, key to surviving in the deep ocean.
• Male false killer whales grow up to 6 m (20 ft) long and weigh about 2,200 kg (4,900 lb), while females top out at 5 m (16 ft) and 1,200 kg (2,600 lb). This size makes them the fourth-largest oceanic dolphin, only smaller than orcas and the two pilot-whale species. Their bulk enables them to tackle large prey like tuna and even juvenile sharks.
• False killer whales form pods of up to 50 members, but can aggregate into super-pods of several hundred, sometimes exceeding 500 individuals. Long-term bonds are evident: some whales have stayed with the same pod for 15 years. This matrifocal social structure, with mothers leading groups, mirrors that of sperm whales and pilot whales, highlighting complex family dynamics rare among dolphins.
• A single pod of false killer whales once numbered 835 individuals on 9 October 1946 at Mar del Plata, Argentina.
• In Hawaii, false killer whale numbers have dropped 75 % between 1989 and 2009, likely due to entanglement in fishing gear and hook ingestion. Their high position in the food chain makes them prone to organochloride buildup.
