The abyssal zone is the layer that is present deep inside the ocean near the floor of the ocean. This region starts at about 13,000 ft. and extends to 20,000 ft. The abyssal zone is very deep and it is extremely difficult for the sunlight to reach this region. Consequently, the communities existing in that region remain in complete darkness.
The temperature is almost near the freezing point due to the lack of solar radiation. The pressure in this zone is 200 to 600 more than that of the surface due to the amount of water that covers the abyssal zone. Deep-sea anglerfish and tripod fish inhabit this region despite harsh conditions.
