Considered a toothed whale, Orcas are actually the largest member of the dolphin family and are easily spotted by their highly distinctive dorsal fin. Jet black coloring on their top and white underneath, the Orca also wears a white oval spot behind and below its eye. Incredibly powerful, these marine creatures travel in groups or pods and hunt anything from seabirds, squids, seals, sea lions and even sharks or other whales.
