MORE ON THIS: False killer whales, while a globally distributed species, have a special tie to Maui and the four-island region. Recent research has found that a very small group of this odontocete, or toothed whale species, calls Hawaiian waters home, making them genetically different from offshore groups. This makes this population especially interesting because false killer whales are generally thought to prefer deep ocean environments far from any land.
Genetic tests were completed on samples collected from groups of false killer whales around the main Hawaiian islands and locations throughout the North Pacific. Researchers found samples collected from individual whales close to the Islands were most genetically unique when compared to samples from whales in the Pacific Ocean, Panama and Mexico. The uniqueness of the samples indicates there are two separate populations; an inshore population and an offshore population.
Their acrobatic displays and tendencies to bow ride make false killer whales hard to miss if you are lucky enough to see one. Hawaii insular population numbers are predicted to be as low as 123 individuals, with only 46 capable of breeding. There is good news though. The insular false killer whale population was classified as an Endangered Species in 2012, meaning this population now has extra protection. Keep your eyes open. If you’re lucky you will see one of Hawaii’s very own false killer whales.
