How do hatchet fish protect themselves?
Hatchetfish, tiny "alien-looking" creatures known for an uncanny ability to hide out in open water, use mirror-like scales to deflect and diffuse light to make themselves invisible to predators, scientists reported Wednesday.
How does the hatchetfish hide from predators?
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.
What type of animal is a Hatchetfish?
What type of animal is a hatchetfish? A hatchetfish (Gasteropelecus sternicla), belonging to the family Gasteropelecidae, is a species of fish that can be found in deep water and freshwater. The fish got its name because of its unique hatchet-like appearance.
What ocean zone does the Hatchetfish live in?

How do Hatchetfish reproduce?
Breeding. Silver Hatchetfish deposit their eggs on floating plants, but beyond that, not much is known about their breeding habits. There have been some reports that soft water with a lower pH and a diet rich in insects encourage spawning.
What are tubular eyes?
Derived from a lateral non-tubular eye, the tubular eye is comprised of a thick main retina, subserving the rostrally or dorsally directed binocular visual field, and a thin accessory retina subserving, the lateral, monocular visual field.
Does the Hatchetfish live in the Twilight Zone?
Animals that live in the twilight zone must be able to survive cold temperatures, an increase in water pressure and dark waters. ... Octopus, squid, and the hatchet fish are some of the animals that can be found in this zone. Many animals in this zone have thin bodies that help them hide from predators.
What does a deep sea Hatchetfish look like?

How do you keep 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.
