The Great White Shark
The sea is an ocean of mysteries, and none of them is more fascinating to me than the creature that some call 'man-eater' or 'white death'. It is the vision of terror summoned by an active imagination when one swims out too far from shore, a vision that evokes mankind's collective nightmare of being eaten alive. It is Carcharodon carcharias; it is the Great White Shark. What do Great White Sharks look like? The Greek name, (Genus species) for the Great White Shark is Carcharodon carcharias carchar meaning ragged and odon meaning tooth. It is in kingdom-animalia, phylum-chordata, subphylum-vertebrata, order-lamniformes, family-lamnidae, and class-don't know. The Great White Shark's body can grow from 4 ft to 23 ft. It's skeleton is cartilage and 63% of the body is muscle. Sharks have a pointed snout that extends forward and over a crescent-shaped mouth set with triangular shaped teeth. The Great White Shark can have 20 rows of saw blade like teeth. The female shark is larger than the male. Only a few species, including the White, the Mako, and the Tiger shark, have the large fearsome teeth popularly thought of as typical sharks. The Great White Shark's swimming speed can be up from 20 to 30 MPH. Color consists of blue on the
Sharks are sensitive to light and can detect objects even in murky water. Some have a mirror like layer under the retina that allows more light into the eye. Sharks do have ears, but the role of hearing in the shark's location of prey is not well understood yet. A shark can detect sound waves and disturbances in the water with its lateral line or lateralis system. This is a series of thin canals, filled with water that runs along the side of the body. The canals are attached to nerves that send signals to the brain. Sharks can also sense electricity and magnetic fields. Sensory pores located on the shark's head can detect prey's bioelectric field even if the prey is buried in sand. A shark can also detect the earth's magnetic field. Open-ocean sharks may use this information to navigate and orient themselves. The life span of the average shark consists of about 10 years. The shark's only line of defense is its teeth. Sharks must always keep swimming. If they stop, they will sink to the bottom and drown. This is because all sharks do not have a swim bladder, which is a small bag-like part of their body, which holds air. This swim bladder is found in most fish, but not sharks. They must keep the water moving across their gills to get oxygen at all times to breathe. Could Humans have prevented sharks from becoming endangered? The great white shark roams in many of the world's seas and oceans. The great white spends most of its time in shallow coastal areas around reefs where there is plenty of prey. In conclusion I think that the great white is a magnificent creature and we need to accept that if we see an animal we don't know much about or hear about attacking someone, don't hurt it or kill it. If it does bite someone it's because they were in is territory, and he mistook it for
