Tubeworms like these Oasisia alvinae are abundant at hydrothermal vents at depths of 3,700 meters (12,140 feet) in the Pescadero Basin, located off the east coast of Mexico’s Baja California.

Copepods like the one in this video can be found in massive numbers across the world ocean. They play an important role in ocean food webs as predators—they eat even smaller diatoms and phytoplankton—and prey for animals like jellies, fish, and filter feeders.

MBARI researchers used ROVs to study pearl octopus (Muusoctopus robustus) mothers nesting near warm seafloor springs. Unlike other deep-sea octopuses, their eggs hatched in under two years. The extra warmth boosted metabolism of the moms and their broods.

A striking white coloration makes this spiny skate (Bathyraja spinosissima) easy to spot. These active swimmers hover and glide well above the seafloor, while their relatives tend to stay close to the bottom. This species is especially common in rocky lava fields.

Atolla gigantea is the largest Atolla species found off the West Coast. This deep-sea crown jelly can reach a diameter of up to 15 centimeters (six inches) and is one of the most widely distributed jellyfish. The genus occurs worldwide, from the Arctic to the Antarctic.

These tiny animals build mucous houses to filter marine snow sinking from the waters above. When their filters clog, they abandon their homes, which sink to the seafloor packed with nutrients and large amounts of carbon: youtu.be/7swiAc8rZbk?...

Rattails, or macrourids, are common throughout the world’s ocean. Big blue eyes give the rattail an edge at finding food in deep, dark waters. Their keen eyesight reveals prey, like fishes and squid, darting just above the seafloor.

Alciopid polychaetes have large, complex eyes with corneas, irises, lenses, and other structures that give them excellent vision. 👀

Deep-sea hatchetfishes cleverly camouflage themselves in the dark depths of the ocean with light-producing organs along their bellies. This allows them to match the daylight filtering from surface waters above and hide from predators lurking below.

A resident of rocky environments, the mushroom soft coral (Heteropolypus ritteri) offers a haven for small animals seeking protection. A snailfish may hide near the umbrellas of stinging tentacles, or a shrimp might hang on to weather the storm of strong currents.

Sea pigs (Scotoplanes sp.) are one of the most commonly sighted animals on the seafloor off Monterey Bay—but plentiful hardly means boring. Unlike most sea cucumbers, sea pigs use their long, stilt-like tube feet to suspend their bodies above the soft mud.

This anglerfish belongs to the family Lophiidae, also known as the goosefishes. This group of alluring anglers uses their speckled coloration to blend into the sandy seafloor on the continental shelf.
