FACT OF THE WEEK: False Killer Whales Call Hawaii Home

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.

A long journey home

Another terrific whale season is almost complete in Hervey Bay, Australia, as Pacific Whale Foundation’s research team come to the tail end of collecting fluke identification and distribution data that will be compiled with 30 years of research in the area.

Southern hemisphere humpback mothers and calves are the last to be spotted as they complete their annual southward migration to the Antarctic feeding grounds. PWF researchers are assimilating data to take back to our research headquarters on Maui, where photographs and findings will be analyzed.
