Cold Blooded Swimmers Fish. Small microscopic plankton are carried by the ocean. Fish, however, are nekton; swimming independently of the ocean waters force. Fish can be defined as follows: Cold-blooded vertebrates that live in water Use fins to swim Breathe through gills.
Cold Blooded Swimmers Fish. There are three classes of fish: Agnatha (jawless fish) & cartilaginous fish both have skeletons of cartilage. Bony fish have skeletons of bone. - Cartilage = firm, but flexible material that makes up the skeletons of sharks, rays, lampreys, & hagfish. The three types differ in Body covering Types of fins Methods of buoyancy, or remaining afloat.
Cold Blooded Swimmers Fish. Buoyancy = tendency to remain afloat in a liquid or gas. Fish need a mechanism to remain buoyant & free to move around in search of food & habitat.

Cold Blooded Swimmers Sharks: Mostly Peaceful, Longtime Inhabitants of the Sea Perception by the public is that sharks are dangerous maneaters; sharp teeth chomping off body parts. Attacks are not as common as the media leads us to believe. < 100 people a year & very few result in death. More people are hit by lightning each year. Regardless, media continues to mark them as a constant & overwhelming threat to beachgoers.
