🎥: Franco Fabioh · These intelligent marine mammals reign the underwater world! Orcas use social signals (squeaks, whistles, and chirps) as well as bursts of high-frequency bio-sonar, which we hear as buzzes and clicks. The Eastern Tropical Pacific (ETP) population of orcas roam the waters of Mexico, Central America, and occasionally are spotted off of Southern California! ETPs follow where the food goes - they have a generalized diet ranging from smaller dolphins, rays, and other fish. | Ocean
