Deep-Sea Fish

Living in total darkness. Deep-sea fish live so far below the ocean's surface that no sunlight ever reaches them. They've adapted amazing abilities like bioluminescence, which means they can create their own light to communicate, find food, and attract mates.

Lanternfish dominate deep seas. The lanternfish is the most common deep-sea fish in the entire ocean. These small fish have rows of light-producing organs running along their bodies that twinkle like tiny lanterns in the darkness.

Extreme fishing techniques. Anglerfish use one of nature's coolest tricks: females dangle a glowing lure on a fishing-rod-like extension from their heads to attract prey in the darkness. When prey bites, the anglerfish swallows it whole because food is scarce down there.

Bristlemouths are tiny champions. Bristlemouths may be one of the smallest deep-sea fish, but they're incredibly successful and live at extreme depths where few other creatures can survive. Scientists believe they might be the most abundant vertebrate in the entire ocean.

Viperfish show their teeth. Viperfish have massive fangs that stick out of their mouths even when closed, and their teeth are so big they can't fit in their mouth properly. These fearsome-looking hunters swallow fish larger than themselves by unhinging their jaws.
