What does a deep sea hatchetfish look like?

Hatchetfish are well camouflaged. Like many deep sea fishes, they have light-producing organs in rows along their bellies. These organs shine a pale blue light that matches daylight filtering down from above, and hides them from predators below.

Are Hatchetfish peaceful?

Tank Mates The peaceful Common Hatchetfish makes a better community tank mate than Silver Hatchetfish since the Common is not as shy as the Silver, so they won’t get stressed out by having other species sharing their space.

How deep do Hatchetfish live in?

They are abundant in warm and temperate regions throughout the world, usually at depths of about 200–1,000 m (650–3,000 feet). Deep-bodied and flattened from side to side, they have slender tails and rows of light organs along the lower edge of each side of the body.

How do you take care of hatchetfish?

Common hatchetfish prefer soft water (as their native Amazonian waters have very low water hardness); maintain 2.0 to 14.0 dGH. Temperatures should range from 72⁰ to 81⁰F. As you might imagine, the water should be slightly acidic. A pH of 6.0 to 6.8 is best, though acclimated specimens may adapt to 7.0 to 7.2.

Deep Sea Hatchetfish (Argyropelecus gigas) Hatchetfishes are one of the many deep sea creatures that have the ability to create their own light through a process known as bioluminescence. These fish have special light-producing organs known as photophores that run along the length of their body.

How are hatchetfish camouflaged in the deep sea?

Even in the pitch-black darkness of the deep sea, the faintest silhouette could give up the location of a little fish to a bigger fish lurking nearby. So along with their slender shape and reflective scales, marine hatchetfish have equipped themselves with a row of light-emitting organs called photophores to conceal their shadows.

What kind of fish is a luminescent fish?

Deep-sea anglerfish, hatchetfish, and lantern fish are among the best-known luminescent fishes. In most such fishes, luminescence is produced intracellularly; the light is emitted by special cells called photocytes.

Is the dorsal fin of a hatchetfish transparent?

In some species, such as the highlight hatchetfish ( Sternoptyx pseudobscura ), large sections of the body at the base of the anal fin and/or caudal fin are transparent. They have perpendicular spines and blade-like pterygiophores in front of the dorsal fin.
