The Earth is a wonderful place and the ocean is a fascinating place. The deep oceans have secrets hidden within them. As humans, the more we try to explore these deep dark waters, the more we get surprised. The more we find out about the species inhabiting these untouched waters, the more they surprise us by their presence. And the fact is that time and again, we humans have been challenged by the science of deep-sea biology.

Underwater explorers work under great pressure. Yes, the literal pressure of water increases every ten meters depth per square inch of surface area. Yet, they gather information with the help of science and technology.

These explorers have found many species in these deep-sea waters with different modified characteristics. Bioluminescence is one such characteristic feature of most of the creatures living in the depth of the oceans. An adaptation to probably see in the deep waters where light finds no road. One such fish species is the Ipnops murrayi. Little is known about this fish.

This family of fishes has a slender body. In this genus, the most prominent species are Ipnops meadi (also known as Grideye fish) and Ipnops agassizii.

How many Ipnops are there in the world?

Exact information on the population count of Ipnops fishes is not available.

Where does an Ipnops live?

Ipnops murrayi are found in the Atlantic and Indo-Pacific Oceans, and their distribution varies with the depth they are found in. Grideye fish of this genus are found in deeper waters.

What is an Ipnops’ habitat?

Ipnops murrayi fishes prefer to live near the ocean beds in the bathyal and abyssal zones. Among Ipnops murrayi, Ipnops agassizii and Ipnops meadi (also known as grideye fish) of this genus, the distribution of the first two are found above 9,842.5 ft (3000 m) sea depth, and grideye fish distribution is found below 10,826.8 ft (3300 m) sea depth.

Who do Ipnops live with?

Ipnops murrayi live in groups.

How long does an Ipnops live?

These species were first discovered in 1878 by Dr. Albert Günther when he was on an expedition on HMS Challenger.

O.Munk, of the Institute for Comparative Anatomy and Zoological Technique, wrote about the species in his write-up entitled ‘The Eyes of Ipnops Murrayi’ in 1878.
