This is a description of an octopus living in the deep sea. It is a fascinating creature, with its eight tentacles and bulbous head. It has the ability to change color to blend in with its environment, and its eyes are able to see in the dark depths of the ocean.
In zoology, deep-sea gigantism, or abyssal gigantism, is the tendency for species of deep-sea dwelling animals to be larger than their shallower-water relatives across a large taxonomic range. Proposed explanations for this type of gigantism include necessary adaptation to colder temperature, food scarcity, reduced predation pressure and increased dissolved oxygen concentrations in the deep sea. The harsh conditions and inhospitality of the underwater environment in general, as well as the inaccessibility of the abyssal zone for most human-made underwater vehicles, have hindered the study of this topic.
