How x ray fish protect themselves?

Camouflage: X-ray fish have transparent bodies that help them blend in with their surroundings, making them difficult for predators to see.

Bioluminescence: Some species of x-ray fish can produce light using bioluminescent organs. This ability allows them to camouflage themselves by matching the ambient light in their environment.

Countershading: Some x-ray fish have darker pigments on their upper bodies and lighter pigments on their lower bodies. This coloration pattern helps them blend in with the background when viewed from below or above.

Startle response: If an x-ray fish is threatened, it may suddenly flash its transparent body or produce rapid flashes of bioluminescence. This startling display can confuse predators and give the fish time to escape.

Schooling behavior: X-ray fish often live in large schools, which provides them with an additional layer of protection against predators. Predators are less likely to target individual fish in a large group, as the sheer number of fish can be overwhelming.
