Answer:

Coelacanth

Explanation:

coelacanth is the extinct species that were present some 80 million years back on earth. These are large fishes with hollow spines that are attached to their bodies. They were usually of length approximately 2 meters and their body weight was about 200 pounds. From the research, it has been found that they live for nearly 60 years or even more than that. They have a distinct type of adaptive nature commonly called tapetum that is usually found to be present in the case of dolphins and dogs and their eyes are very much sensitive to the light.

By using the radioactive dating method, it has been determined that these fossilized coelacanth species were present about 350 million years back. This organism was recently caught off the coast of Madagascar in 1938.

A culture can be defined as the general way of life of a group of people living together in a particular location or society.

Basically, culture comprises of beliefs, values, behaviors, language, dressing, cuisine, music, symbols, arts, social habits, knowledge, customs, laws pertaining to a particular group of people living together in a society.
