Creatures of the Abyssopelagic Zone

It is said that humans have more knowledge about the infinite universe than about the ocean below. Three-quarters of the area of the deep-ocean floor lies in the Abyssopelagic Zone The water stretches over 6,000 ft. deep. In this article, I am going to write about one layer and one topic of the vast ocean. I will cover an overview of the animals whose home is in the Abyssal layer.
It takes a special kind of animal to live 13,123 feet below sea level, not seeing any sunlight, living in eight tons per square inch of atmospheric pressure, (which is about a thousand times the standard atmospheric pressure at sea level.) Because it is so far from sunlight, the temperature is constantly near freezing. Animals living here must use bioluminescence to communicate.
Bathynomus giga is the Latin name for the giant isopod. These creatures can grow up to 16 inches, and their closest cousin is the land dwelling roly-poly. isopods are bottom feeders who comb the ocean floor looking for decaying plant and animal material.
The next animal I am going to talk about is the rattail fish. Its scientific name is Coryphaenoides acrolepis. These fish have extremely long life spans, living up to 73 years. Their job is to be an apex predator of that ecosystem.
The tripod fish is a little bit of a deceiving name; it looks more like a drifting jellyfish. It got its name because of the long, stick like fins. This fish is known is the “stick walker”, and it ambushes its prey.
The vampire squid is a harmless scavenger. Its long feeding filaments collect drifting debris, which normally includes marine snow. Its unique characteristics make it not a squid, but a strange cephalopod whose features help it survive the dark ocean depths. There isn’t much information on the bioluminescent anglerfish, but we do know it has a bioluminescent light to lure its prey.
