Evidence of resident coastal population(s) of false killer whales (Pseudorca crassidens) in northern Australian waters
To help evaluate the distribution, residency, population size and structuring (and hence conservation status) of the poorly known false killer whale Pseudorca crassidens in northern Australian waters, we undertook studies of sightings, movement patterns based on satellite telemetry, and genetics.
