Deep Sea Hatchetfish
Deep Sea Hatchetfish
Location: Oceans around the world especially South and Central America.
This is the kind of creature that came straight out of your nightmare to suck your soul out! But this deep sea fish lives in depths which have little or no light penetration at all. Because of this, their eyes are adapted to recognize even the slightest shadows in the water. Believe it or not, these creatures have the ability to create a light of their own through a phenomenon known as bioluminescence and sometimes they can actually adjust the level of light below them to match the surface light, which makes them practically invisible! Scary indeed!
Found in tropical, subtropical and temperate waters of the Atlantic, Pacific and Indian Oceans, marine hatchetfishes range in size from Polyipnus danae at 2.8 cm (1.1 in) to the c.12 cm (4.7 in)-long giant hatchetfish (Argyropelecus gigas). They are small deep-sea fishes which have evolved a peculiar body shape and like their relatives have bioluminescent photophores. The latter allow them to use counter-illumination to escape predators that lurk in the depths: by matching the light intensity with the light penetrating the water from above, the fish does not appear darker if seen from below. They typically occur at a few hundred meters below the surface, but their entire depth range spans from 50 to 1,500 meters deep
