There are many facts about killer whales that are interesting to note.The killer whales of the ocean have interesting feeding habits that are different than many of the other whales in the ocean. The killer whale is a carnivore and actively hunts for its food. This can be seen as a very distinguishable trait in the killer whale as whales such as the blue whale and the right whale only eat small organisms to survive. The killer whale is also smaller than the blue and right whales. The orca whale has a large and round shaped mouth that is well adapted to hunting with its conical teeth. These teeth point backwards and in on the whale making the whale ideal in terms of ripping apart the animals it preys on. The teeth on the upper portion of the mouth of the orca whale actually interlock making it that much easier to hold onto prey and to tear prey into smaller pieces for better digestion. The diet of the killer whale may vary according to where they are located. Many researchers have presented the idea that the varying food preferences of the killer whale may have led to the distinctions in population types that we see with these whales. There are three types of population types including transints and offshores as well as resident populations of killer whales. These various population types have been seen all over the world in various places.
Transient killer whales most often feed on various species of seal as well as sea lions, squids, and sharks. The transient killer whales also may feed on penguins, smaller whales and even the large baleen whales that are in many oceans across the world. When it comes to resident whales they types only feed on a variety of fish such as salmon and herring while the diet of the offshore orcas is currently unknown.
