Habitat: Midwater

Whalefish

A whalefish lives in a world without sunlight. This rarely seen deep-sea fish relies on a network of pores to feel vibrations in the water and sense its surroundings.

Deep-sea anglerfish

The anglerfish is one of the most famous deep-sea animals, with a bioluminescent “fishing pole” projecting from its head to lure prey.

Vampire squid

Swift and mysterious, vampire squid are an icon of life in the deep midwater.

Barreleye fish

The barreleye fish has a transparent head and tubular eyes.

Bloody-belly comb jelly

The bloody-belly comb jelly’s deep red color disguises it in the ocean’s midnight zone.

Bomber worm

The midnight zone is a world of total darkness where predators lurk in the shadows ready to pounce on prey. The small bomber worm (Swima spp.) swims in the waters a few meters above the seafloor. A wriggling worm is exposed out in the open, but it has a secret weapon to avoid becoming a meal for a hungry predator.

Red siphonophore

The spectacular scarlet color of the red siphonophore is camouflage in the ocean’s midnight zone.

Whiptail gulper eel

Food is scarce in the deep sea, so a gulper eel’s oversized mouth helps it swallow any morsel of food—big or small—that it comes across.

Big red jelly

The big red jelly lurks in the ocean’s mysterious midwaters.

Angler siphonophore

The angler siphonophore fishes for its meals.
