Type: 

Mammal

Distribution: 

Short-finned pilot whales are circumglobal in temperate and tropical waters. Long-finned pilot whales occur in temperate and polar waters.

Population: 

Unknown

Bycatch Threat: 

Longlines, gillnets, purse seines, trawls

IUCN Status: 

Data Deficient

Bycatch of pilot whales (short-finned) occurs in the pelagic longline fisheries targeting swordfish, tuna, and shark in the U.S. Mid-Atlantic.  There are also records of pilot whales (long and short-finned) being taken in gillnet, trawl, and purse seine fisheries. "Whale-safe" hooks are being tested in the longline fishery that aim to reduce pilot whale bycatch by allowing whales to straighten the hook, while being strong enough to retain target catch.
