Live in close knit pods of 2 or more orcas. Each pod has its own dialog. Males spend their entire lives with there mothers, while females leave at sexual maturity. White belly, chin, and sides, pure black back, and gray saddle behind dorsal fin. None, the orca is the top predator in the sea.
Humans are the only danger to healthy orcas.
On males it is straight and a as tall as 7ft, and females it is curved and about 3ft tall. The large round flippers used for steering. It's powerful tail it uses to propell itself through the water. Unlike fish, it moves its tail up and down. Also, I couldn't place this on the graphic, are 3 slits on females and 1 slit on males, located midway between the pectoral flippers and fluke.
