The habitat of 500 different shark species can be found in all of the oceans and the vast majority of the seas throughout the world. Because water covers an enormous percentage of the earth’s surface, this implies a significant number of sharks inhabiting its depths.
What Is A Shark’s Habitat?
There are a small number of shark species that are able to live in freshwater rivers and lakes. Most sharks live between the water’s surface and 2000 metres down.
It is rare to find sharks living at 3000 metres or more below sea level, but it has been witnessed.
Great White Shark Habitat
The Great White Shark prefers the open ocean while most sharks are found in the area up to 2000 metres below sea level, certain species prefer specific levels, mainly due to the prey available and the temperatures experienced at those depths.
Sharks That Live On The Ocean Floor
Those that skate along the ocean floor are known as benthic sharks and include the Wobbegong, Angleshark and Zebra Horn Shark.
The Bull Shark frequently leaves its oceanic habitat and travels into freshwater rivers, such as the Mississippi, which has actually needed to be equipped with special means of stopping these animals from swimming miles up.
Most Sharks Prefer To Live In Shallow Continental Shelf Areas
The oceans hold about 96% of the entire water supply for the earth. However, different areas possess different characteristics (topography, proximity to land, depth, temperature, and so on). Therefore, some areas are densely populated by marine plants and animals, while others are less so.
Sharks tend to prefer the shallower continental shelf areas. This is because these are the areas at which rivers deposit nutrients into the oceans.
Do Sharks Prefer Warm Or Cold Water?
Tiger Sharks, Hammerheads and Bull Sharks prefer warmer waters, while the Dogfish, Greenland and Goblin sharks opt for chillier waters. The Mako, Blue, Thresher and Basking sharks are happy in temperate conditions.
Do Sharks Change Their Habitat?
Certain shark species will remain in a fairly confined habitat for their entire lives. Others, such as the Blacktip and Tiger sharks, may migrate for short distances (up to 1000 miles).
Having to traverse such extensive areas means that those species require special adaptations to allow for the changes in temperature, topography and perhaps even prey.
The Vital Role Of A Shark
While humans tend to interfere with nature’s equilibriums, sharks play a vital role in maintaining them. Therefore, the value of the river’s nutrients cannot be underestimated when considering sharks chosen habitats and the viability of their survival therein.
Nutrients feed the marine lives in this water from a cellular level, which, in turn, feed larger and larger species. The chain continues until it reaches predators such as sharks and even human beings, who feed off fish, crustaceans and molluscs.
