Why do sharks migrate?
Sharks have been known as early as more than four hundred years ago. Sharks are one species of fish that possesses a full cartilaginous skeleton with a highly streamlined body. Known to mariners as sea dogs, the name shark was first coined by the sailors of Sir John Hawkins in 1569, in reference to the large sharks seen in the Caribbean Sea. Later on, the term was used as a general term for all kinds of sharks. As a solitary hunter in the vast seas and oceans, sharks invade the water primarily in search for food. Studies conducted among sharks showed that at an average speed of 8 kilometers per hour, sharks are just cruising. But when they are able to find food and attack its prey, sharks can speed up to twice its average speed. Along with its speed, sharks are known to have powerful problem-solving skills, social skills and curiosity, defying the notion that sharks are animals purely driven by instinct.
Interesting as they are, sharks inhabit the waters and are common down to depths of 2,000 meters and some live even deeper. Sharks are known to transfer form one oceanic region to another. The migratory habits among sharks have been scientifically studied and are currently categorized into local sharks, coastal pelagic sharks and highly pelagic sharks. Local sharks are basically non-migratory sharks and just stay within 100 miles. Coastal pelagic sharks migrate along the shallower waters for a distance of over 1600 kilometers, following certain currents. And highly pelagic sharks follow currents across oceanic borders to migrate. Sharks often migrate due to changes in temperature, adequate search for food and to find sufficient means for survival.
Because of the image set from history, sharks are one of the most feared mammals that exist.
