Short Finned Pilot WhaleSmall and Cute
Short Finned Pilot Whale - Globicephala macrorhynchus
One of the larger members of the dolphin family, Short-finned pilot whales reach lengths of between 12ft for females and 18ft for males, with some males reaching 24ft. Full grown adults can weigh between 1-3 tons and usually travel in groups between 25-50 animals. Pilot whales are polygynous, which means males will have more than one mate. Their pods are normally composed of one male for every eight mature females. Females will remain with their birth school whereas the males will leave their birth school shortly after maturity.
Pilot whale gestation last approximately 15 months while lactation lasts over two years. Females normally have a calf every five to eight years from the age of 10. Males will leave up to 45 years with females living for 60 years.
- Bulbous melon head with no beak.
- Dorsal fin located far forward on the body with a relatively long base
- One of the largest dolphins growing to 18ft in lenghts
- Travel in pods of 25 to 50 individuals, unlike most whales
Short-finned pilot whales are found throughout tropical and subtropical waters
worldwide, with emphasis on water deph as opposed to distance from shore. There are four recognized groups of these animals in North American waters: West Coast, Hawaii, Northern Gulf of Mexico, and Western North Atlantic. In more recent population estimates, the total short-finned pilot whale population numbers around 45,000 animals in waters off North America. Because of their migratory nature, there is little data on this species as to their migratory patterns and habits.
As with most marine mammals, entanglement is the primary threat to their survival. This usually occurs through several types of
commercial fishing gear such as gillnets, longlines, and trawls. Ship strikes may also be a problem around Hawaii, as several individuals have been found with propeller injuries.
