Shark Species Profiles Background: Sharks have existed for about 400 million years, before dinosaurs roamed the earth! They belong to a class of fish called Chondrichthyes. Chrondrichthyes means "cartilaginous fishes". Theskeletons of sharks and other Chondrichthyans are made of cartilage unlike human skeletons that are made of bone. Although all sharks have some similarities such as having gills and fins, theycome in a variety of shapes, sizes, colors, and personalities. They also live in many different habitats and in different parts of the world. Materials: There are 8 shark species profiles included in this activity with information on size, color, diet, and habitat of each shark. Focus is on sharks that live in waters off the Florida coast althoughsharks from other parts of the world are also included: 1.2. Bull sharkWhite shark 3.4. Tiger sharkGreat hammerhead shark 5.6. Shortfin mako sharkThresher shark 7.8. Whale sharkLeopard shark
In addition, there are also species profiles on closely related rays, skates, and sawfish that mayalso be included in classroom learning activities: 1.2. Atlantic stingrayClearnose skate
Classroom Activities:
Carcharhinus leucas Bull Shark
Length: Maximum length of 11.5 feet (3.5 meters) Color: Pale to dark gray above fading to a pale or white underside Diet: Fish and small sharks Habitat: Marine and freshwater shallow habitats Geographical Location: Live throughout the world
Galeocerdo cuvier Tiger Shark
Length: Maximum length of 14 feet (4.25 meters) Color: Bluish-gray to dark gray or black on top with a yellowish-white underside, dark spots are visible on young sharks but fade as the shark matures Diet: Sea turtles, rays, sharks, bony fishes, sea birds, dolphins, squid, and crustaceans Habitat: Marine, murky waters off the coast from the surface to depths of 1,085 feet (350 meters) Geographical Location: Temperate and tropical waters throughout the world, with the exception of the Mediterranean Sea

Thresher Shark Alopias vulpinus
Length: Maximum length of 24.9 feet (7.6 meters) including the long tail fin Color: Dark brown and slate gray to black on top with black spots near the tail, it is white underneath Diet: Small bony fish such as herring, bluefish, and mackerel, they use their long tail fin to stun their prey so it is easier to catch Habitat: Marine, coastal waters to open ocean waters at depths to 1,800 feet (550 meters) Geographical Location: Cold temperate and tropical waters throughout the world's oceans

Atlantic Stingray Dasyatis sabina
Length: Disk width of 12-15 inches (stingrays are measured this way) Color: Brown or yellowish brown on the top, becoming lighter close to the edge. The underside is white or light gray Diet: Clams, worms, tube anemones, and bivalves Habitat: Marine and brackish water in warm coastal areas, it also lives in some freshwater lakes in Florida Geographical Location: Western Atlantic Ocean from Chesapeake Bay south to Florida and into the Gulf of Mexico
Clearnose Skate Raja eglanteria
Length: Maximum disk width of 19 inches (48 cm) Color: Dark to light brown or gray on the dorsal surface with dark spots and bars sometimes present, the ventral surface is white Diet: Shrimp, crabs, and small fish Habitat: Marine inshore waters Geographical Location: Atlantic Ocean – from Massachusetts south through Florida and into the Gulf of Mexico
