History on Deep Sea Biology

Anusha Polampelli

The sea is outlined because a part of the ocean below two hundred meters depth. These surroundings are considered extraordinarily harsh with temperatures of below five degrees Anders Celsius, extreme pressure (2,000 meters equals regarding two hundred times the gas pressure bewildered level), and no daylight. The deep ocean starts wherever the daylight starts to fade, around 200m below the surface of the ocean. A twilight zone extends right down to 1000m when which just about no lightweight penetrates. The water is cold, reaching 3ºC, and contains little or no chemical element. Fish living nearer to the surface of the ocean could have an air bladder – that is an outsized organ with air in it, that helps them float up or sink down within the water. Deep ocean fish have not got these air sacs in their bodies, which implies they do not get crushed.
