A new look at footage recorded by one of MBARI’s deep-sea robots during an expedition to the Gulf of California has revealed a new deep-sea squid that broods giant eggs.

Breaking news: We believe that this tiny crab was indeed trying to hide from Monday.
During ROV dives in the Monterey Bay, MBARI researchers often observe small crabs riding on the backs or clinging to the bellies of Scotoplanes sea cucumbers, also known as sea pigs.⠀
The view from below.
This species, Careproctus longifilis, is also known as the threadfin snailfish. These deep-sea snailfish are found at depths between 1,900 and 3,334 meters (6,230 and 10,940 feet) and measure up to 15 centimeters (about six inches long).
A whalefish?!? 🐋🐟
Originally described as resembling baleen whales, these fish are incredibly rare. We have very few images of species in the family Cetomimidae, but we were lucky enough to capture this spectacular footage this year!

The fellowship of the deep. 🧙🏼✨
It's uncommon to see gatherings like this in the deep abyssal plain. These invertebrates—an octopus, tanner crab, and a couple of sea cucumbers and anemones were observed off the coast of Half Moon Bay at 1,949 meters (6,395 feet) deep.
MBARI staff have shown off their deep-sea Halloween costumes in the office today. 👻 This bioluminescent jelly is one of our favorites.

Spending some quality time with the sparkliest octopus. ✨
Japatella diaphana lives exclusively in the midwater from a few hundred to over 1,000 meters. Chromatophores with pigment-containing and light-reflecting cells allow it to change its skin color.
On the seafloor, in cracks and crevices on the edge of Davidson Seamount— an underwater mountain made of ancient lava—scientists got to observe not hundreds, but thousands of octopuses sitting on their eggs!

Octopoteuthis deletron, aka the octopus squid, only has eight arms unlike most squid. They can detach their arm, leaving a wiggling arm with a

What's in a name?
This cranchiid squid, Helicocranchia, has quite a few nicknames from our deep-sea biologists. It's called the pig-nosed, helicopter-tailed, and hippo-squid, depending on who you ask, of course. What nickname would you give it?
Had a starring contest with an owl fish--we lost.
The owlfish, named for the size of its large eyes relative to its head, lives throughout the North Pacific. In the Monterey Bay, we observe these fish between a few hundred meters to over 2,000 meters (6,561 feet).
It's an octo-party!
#FridayMotivation
These juvenile red octopuses, Octopus rubescens, are swarming around an egg yolk jelly in the Monterey Bay. These octopuses live in the shallow midwater as juveniles and then settle and live on the seafloor as adults.
From shark fly-bys and googly-eyed squid to toothy-grinned fishes and corals the size of trees, MBARI’s ROVs encountered many spellbinding scenes in the deep this year. Enjoy MBARI’s

Baby lobster always gets us!
This adorable baby is the Eryoneicus larval stage of a deep-sea lobster. It floats and feeds in the water column until it’s ready to change into a juvenile lobster and settle on the seafloor. This one is about five centimeters (two inches) long.
The fangtooth fish has a face only a mother could love. 🌊👹💙
But this fierce-looking fish actually gets no bigger than the average adult human hand. A rare find, we've spotted fangtooth just eight times in the past 30 years of MBARI ROV expeditions.

Gliding into Cephalopod Awareness Days with a mama Gonatus squid. 🦑
MBARI scientists discovered that some female deep-sea squid, like this Gonatus onyx, brood their eggs by carrying them between their arms until the young hatch and swim away.
Ghostsharks, or chimaeras, branched off the evolutionary tree from sharks, about 400 million years ago. We spotted this one, Harriotta raleighana, aka longnose chimaera, 2,241 m deep in the Gulf of California.
#SharkWeek
Another cool ghostshark:
Tiburonia granrojo, also known as the big red jelly, is one of the most remarkable residents of the deep sea. A closer look reveals batteries of stinging nematocysts that cover the surface of the big red jelly. These tiny harpoon-like cells stun the jelly’s prey.
Octopus or squid? 🧐🐙🦑
Octopoteuthis deletron, aka the octopus squid, only has eight arms (like its octopus relatives). This species of squid is impressive in many different ways. Their tentacles are bioluminescent, with light-producing photophores at the end of each arm.
Nothing says holiday cheer like twinkling squid arms ✨🦑✨
Like a lizard that detaches its tail when attacked, the octopus squid (Octopoteuthis deletron) can drop its bioluminescent arm tips, leaving a wiggling arm in the grasp of a confused would-be predator.
This orange cirrate octopus was observed gracefully gliding over the Taney Seamounts. These finned octopuses belong to an order of animals called Cirrata named for the presence of hair-like structures called “cirri” on their arms which may help them capture food.
Fresh from the deep—this mom is a pelagic parent 🦑
During a recent deep-sea dive, MBARI researchers encountered this incredibly rare sight—a deep-sea squid (Bathyteuthis sp.) grasping hundreds of eggs in her arms.

This deep-sea shrimp, Acanthephyra sp., can be found at depths between 500 and 3,000 meters (1,640 and 9,840 feet). Without our ROV lights, this bright red shrimp would be invisible in the darkness of the deep sea.
#SHROMPweek2023
Fresh from the deep!
During a recent deep-sea dive, our team came across one of the most remarkable residents of the ocean’s twilight zone: the strawberry squid (Histioteuthis heteropsis). We spotted this crimson cephalopod 725 meters (2,378 feet) deep in Monterey Canyon.
Most sponges are simple filter feeders—they eat small plankton and bacteria that they ‘filter’ from the surrounding water. But in 2012, scientists discovered a sponge that uses small hooks along its vertical branches to entrap and devour larger, more nutrient-dense prey.
This Solmissus jelly probably gets its color from its prey—another purple jelly!
Deep-sea jellies have many remarkable shapes, sizes, and colors. Using ROVs, researchers have uncovered previously unknown predator-prey relationships between midwater gelatinous organisms.

Holy mola! It’s a whole new year!
The ocean sunfish, Mola mola, can grow up to 10 feet long. With a tiny mouth, this animal slurps jellies as they swim through the ocean. It’s a treat for our ROVs to spot a sunfish as it dives to deeper water to feast on jellies.

Sit back and relax with these soothing jellies. From tiny delicate drifters to giant deep-sea denizens, jellies come in a variety of beautiful and mesmerizing forms.
Don’t be fooled by this dazzling deep-sea dweller; Beroe forskalii is actually a fierce predator.🌟
When it bumps into another comb jelly, Beroe uses tiny hairs that act like teeth to grab onto its prey. It then opens its mouth wide and tries to swallow its meal whole.

Salps are gelatinous invertebrates that live in the open ocean but are closely related to the "sea squirts" (tunicates) seen in tidepools. This species, Helicosalpa virgula, was observed by ROV Doc Ricketts 282 meters deep in Monterey Bay.
