Orca Communities in a Fragile Environment

Orca Communities in a Fragile Environment

Orca communities form different species or ecotypes, each with unique acoustic behaviors, feeding habits and prey preferences. Occasionally, the range of these different orca overlaps but they never interbreed and they rarely interact. Orca are top predators and unfortunately they accumulate pollutants that are transferred through the food web which become stored in their blubber and can be passed along to nursing young.

In the northern hemisphere we have three ecotypes: Offshores, Transient Orca, and Resident Orca.
