Spinner dolphins commonly form large groups, often with other species, including other dolphins and even tuna.  Unfortunately, this has made them a common casualty of the tuna fishery.

	Found throughout the world's tropical oceans.
	Found on reef slopes and out in the open ocean.
	Spinner dolphins feed on fish and squid.
	Spinner dolphins are known for their acrobatics, and frequently jump out of the water and spin through the air. They, like other dolphins, use echolocation to navigate and track prey, and often feed at night.

Humpback whales migrate annually between the food-rich waters near the poles and the warm tropical seas where they breed.  Individual whales have been identified as migrating from Antarctica to Costa Rica, the longest migration by any mammal.

	Humpback Whales are found throughout the world's oceans, migrating between polar and tropical seas.
	Found offshore in the open ocean
	Eat krill and small fish
	Humpback whales are famous for their songs.  The songs, which can last up to 20 minutes and are often repeated for hours on end, are only produced by males during the breeding season and might serve to announce a male's presence to other males or to attract females.  Whales from a given region typically share the same song, but songs differ from region to region.

Yellowfin tuna often school with other fish of similar size.  Smaller individuals are often found in large single-species schools or in schools with other species of tuna, while larger individuals are sometimes found schooling with dolphins or porpoises.

	Yellowfin Tuna occur throughout the world's tropical oceans.
	Yellowfin Tuna are found out in the open ocean.
	Yellowfin feed on fish, crustaceans and squid.
	Yellowfin tuna are fast swimmers, and can reach speeds of 70 kilometers per hour (~45 miles per hour).  They roam widely, and have been known to move over 1,000 km in a year.
