Orcas are cool! The colour is black and white and  It has a fin, live and hunt together.  Orca females they live longer than males.  Orca can be found everywhere.  Orca hunt fish to walrus, seals, sealion, penguin, squid, seaturtles and Orcas can dive to depth of  30m in order to hunt.  I like orca because it eat shark and eat a blue whale and an average sized orca will eat 551 pounds 250kg of food a day and Orcas live in small pod of 640 whales they are very social animals.  That is why orcas are cool!
