Orca Whales (Orcinus orca): Orca or killer whales are the largest member of the dolphin family. Orca Whales are sometimes called the wolves of the sea because of their closely-related pack-like behaviours. They are normally found gracing the southern seas in abundance and tend to travel in small close-knit, family pods. They have a unique colouration pattern, a dazzling contrast of jet black above and bright white markings beneath.
