10 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.
11 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.
12 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.
13 Cold Blooded Swimmers Agnatha: The Jawless Lampreys & Hagfish Existed as far back as 550 million years & still look quite ancient. Do NOT have a lower jaw, instead large have a sucker-like mouth with teeth large & teeth rasp-like & rasp-like tongue. tongue. Lamprey scrapes a hole in prey & sucks the body juices Hagfish also scrapes a hole, but enters prey to feed from the inside
14 Cold Blooded Swimmers Agnatha: The Jawless Lampreys & Hagfish Travel by attaching to more mobile fish. Body structure: Flexible cartilage skeleton Small fins Elongated snake-like body Many lampreys & hagfish make the Great Lakes their home.
15 Cold Blooded Swimmers Lamprey: Ancient Bloodsucking Parasites Earth Unplugged (8:26): Synopsis: Lamprey are infamous for their bloodsucking behaviour but little else is know about the life cycle of these ancient creatures. Lamprey are prehistoric animals that have a bad reputation as bloodsucking parasites but there's so much more to these animals than just their nightmarish mouth parts. Lizzie Daly travels to south west Ireland to find a Lamprey in the wild and learn more about this strange but fascinating species.

22 Cold Blooded Swimmers Cartilaginous Fish: Sharks & Rays Class: Chondrichthyes; vertebrate cartilaginous Denticles: small toothlike structures (scales) that cover the body & all point toward the tail. From nose to caudal they feel smooth From caudal to nose they feel rough (like sandpaper)
23 Cold Blooded Swimmers Cartilaginous Fish: Sharks & Rays Some bear live young young; others lay eggs. Do NOT have air-filled swim bladders to keep them afloat, they must keep swimming to avoid sinking. Many possess large oily livers to help maintain their buoyancy. Two main types of cartilaginous fish: Sharks Rays (stingrays, skates, eagle rays, & manta rays)

26 Guest Teacher Wildlife Detectives: Mystery Sharks of Seattle (51:09): Synopsis: One of the world's largest & most elusive predatory sharks, the sixgill, suddenly appears in Seattle's waters. These creatures typically dwell in darkness several thousands of feet beneath the surface. Little is known about them. What would make them appear in the shallows of Puget Sound? And what does it say about our oceans? Researchers are hunting for answers.

31 Cold Blooded Swimmers Sharks: Mostly Peaceful, Longtime Inhabitants of the Sea Swimming the seas for over 450 million years & have changed very little in the last 300 million.
32 Cold Blooded Swimmers Sharks: Mostly Peaceful, Longtime Inhabitants of the Sea
33 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.
34 Cold Blooded Swimmers Sharks: Mostly Peaceful, Longtime Inhabitants of the Sea 350 known species & only 35 have shown themselves to be dangerous to humans. Hammerhead, mako, & tiger among best known. Most feared = great white shark - Does deserve respect; grows as large as 25 feet in length & one of the fastest swimming of all sharks. - Tends to live in colder waters near large prey = seals
