Dorsal fin diagram with landmarks labeled. Fins allow the sharks to be able to guide and lift themselves. Most sharks have eight fins: a pair of pectoral fins, a pair of pelvic fins, two dorsal fins, an anal fin, and a caudal fin. Pectoral fins are stiff, which enables downward movement, lift, and guidance. A shark relies completely on its sensory organs in all aspects of its life. One of the reasons sharks are extremely good predators is their amazing sensory ability. Their senses are remarkable like no other fish or mammal. Sharks rely on their complex sensory system in all aspects of their life, hunting, feeding, mating and general existence.

Shark skeletons are made of cartilage. This is strong and durable, yet much more flexible and lighter than bone. Being lighter helps a shark to stay afloat and reduces the amount of energy they need to move about. The flexibility of cartilage also allows them to make tight turns quickly. Making them one of the most agile animals in the ocean. The liver is usually the first thing one would notice when peering inside and seeing the shark anatomy. A shark's liver can take up approximately 25% of the total body weight. The liver is detrimental to the shark, and it has two purposes. Fatty reserves are kept in the liver, thus causing it to be a store of energy. Shark teeth are one of the most distinctive and fascinating features of these marine creatures. The adaptation of shark teeth to their specific feeding habits is a stunning example of evolution in action. These highly specialized dental structures are essential to the survival of these animals and are one of the reasons they are such successful predators in oceans around the world. This imbalance causes oxygen in the water to diffuse into the shark's bloodstream, where it is distributed throughout the body. Some sharks have a gill pump, a set of muscles that suck in water and push it past the gills. This works something like our lungs -- the shark can continuously gather oxygen while it is in a still position.

Florida Museum of Natural History Gainesville, FL 32611 352-392-1721 (Research) or 352-846-2000 (Exhibits) Anatomy. The first features that most people notice are their streamlined, torpedo-like shaped body, fins and sub terminal mouths (under their heads). A shark's body is adapted to living in the ocean, where every tail movement requires hard work to move through the dense medium. Many sharks need to keep swimming to breathe, so it is very. Most sharks have two fins along the dorsal line, which stabilize their movements. 10.-Pelvic fins. This pair is located on each side of the back of the body and also work to stabilize the shark's swim. The males have an extension at the inner edge of the pelvic fins, which make up the claspers. 11.-Anal fin. sea, the whale shark, is a cartilaginous fish and may reach up to 12 metres in length! A shark's body form may also depict where it lives. Gigantic filter feeding sharks, e.g. basking shark, found largely in the pelagic zone resemble whales, whilst reef sharks are well adapted for their environment with their wedge-shaped heads for getting into

A shark's liver is relatively large, making up 5% to 25% of its total body weight and takes up to 90% of the space inside its body cavity. A great white shark weighing 3,312 kg (7,302 lb.) had a liver 456 kg (1,005 lb.) in weight. A basking shark liver weighing 940 kg (2,072 lb.) may yield as much as 2,270 liters (549 gallons) of oil. Step 5: Each student chooses a different shark to research, draw and label. Have students each choose a different shark species to research and then draw. Have students write the habitat it lives in and identify and label the animals' external and internal structures and camouflage patterns.
The diagram above does not represent any one species of shark, but rather is a compilation of the features posessed by many different species. While bottom-dwelling (benthic) sharks may posess spiracles to enable them to breathe easier while sitting on the bottom, open ocean (pelagic) sharks that swim continually do not posess them. shark, Any of more than 300 species of predatory cartilaginous fish (order Selachii).An ancient animal, it has changed little in 100 million years. The skin typically is dull gray and tough and has toothlike scales. Most sharks have a muscular, asymmetrical, upturned tail; pointed fins; a pointed snout; and sharp triangular teeth.

Label Me! Printouts. Read the definitions, then label the shark diagram below. (Note: not all sharks have all of the fins and spines defined below.) anal fin - the fin on the lower side of the body near the tail (not on all sharks) caudal fin - the tail fin. eye - sight organs located on the head. Sharks are an extremely dangerous kind of fish, with a lot of people encountering its fierce and powerful self. This creature ranges in sizes covering different kinds of sharks that swim the oceans of the world. The great white shark is known for its damage caused and mammoth structure. And many of the beaches worldwide are closed off to.
