A Humpback Whale breeches in northern Pacific. Humbacks are endangered species of whale.

Humpback Whales can be identified by their unique bumps on their tails and fins.

It is not known why whales breach. Some scientists think it is to remove parasites from the skin, others think it might be a courting or dominance behavior.

A sperm whale calf only hours old, born off the southwest coast of Guam 15 June 2001 swims towards a photographer. The pod was spotted about four miles off the coast of the Agat Marina, on the south-west coast of Guam. Whales are born in live births.

Onlookers examine the baleen of a beached Finback whale. Some whales are filter feeders and use this net-like structure to filter small shrimp called krill out of the seawater.

Other whales, like Sperm Whales, eat larger prey like squid, octopus, fish and even sharks. Sperm whales have been recorded diving to depths of 2500 meters (8200 feet or 27.3 football fields or 1.6 miles below the surface.)

An Orca, or Killer Whale, has very aggressive teeth that let it catch larger prey like seals.

Orca's have unique coloration that distinguishes it from other large ocean-going mammals.
