Known as the Dana octopus squid, Taningia danae belongs to the deep-sea squid family Octopoteuthidae. Reported specimens reach a mantle length of about 1.7 meters and a total length of about 2.3 meters, placing it among the larger squid species. Despite its common name, it is a squid rather than an...

Eight arms rather than an adult squid's usual combination of arms and two long feeding tentacles distinguish Taningia danae. The Dana octopus squid loses its feeding tentacles as it develops, but remains a true squid in the family Octopoteuthidae. Large specimens reach about 1.7 meters in total leng...

Blue light from numerous photophores, specialized light-producing organs, distinguishes Watasenia scintillans, the firefly squid. This small cephalopod inhabits waters off Japan and spends much of its life below the sunlit surface. Its lights occur across the body, with conspicuous organs near the a...

Cold waters of the northeastern Pacific, including those off California, are home to the deep-sea octopus Graneledone boreopacifica. Its reproductive behavior became a notable subject of study when researchers followed a female roughly 1,400 meters below the surface in Monterey Canyon. She guarded t...

An internal shell curled like a ram's horn gives Spirula spirula its common name. This small deep-sea cephalopod is the sole living member of the family Spirulidae. The shell is divided into chambers and helps control buoyancy, allowing the animal to maintain its position without relying entirely on...

Four broad, ribbonlike oral arms give the giant phantom jellyfish an appearance unlike the fine tentacle fringes of many familiar jellyfish. Stygiomedusa gigantea is a rarely observed deep-sea scyphozoan recorded in oceans around the world. Its bell can approach a metre across, while the oral arms m...

The Aquarium de Monaco is located within the Oceanographic Museum, a marine science institution perched on a cliffside in Monaco. The museum was founded by Prince Albert I in 1910 and was famously directed by oceanographer Jacques-Yves Cousteau from 1957 to 1988. Its aquarium facilities consist of n...

Footballfish belong to the Himantolophidae family of deep-sea anglerfishes. These large fish are distinguished by the females’ rounded shape and the males’ unique attachment as obligate parasitic partners. Found in extreme ocean depths, they represent a fascinating example of specialized adaptation...

The Indonesian Coelacanth represents a critically rare glimpse into ancient fish evolution. This lobe-finned fish, scientifically known as *Latimeria menadoensis*, was discovered in deep waters off Sulawesi, Indonesia. It is the second living species of coelacanth ever identified, providing invaluab...

The spookfish, *Dolichopteryx longipes*, is a deep-sea fish notable for its unique tubular eyes. These specialized organs use reflective membranes instead of lenses to focus light, allowing the fish to see upwards through the dark depths. This adaptation is rare among vertebrates. It’s primarily stu...

Opah is a large deep-sea fish belonging to the Lampridae family. It’s notable for being the first confirmed fully endothermic fish, maintaining its body temperature through a unique circulatory system. This adaptation allows it to thrive in the cold mesopelagic zone of the ocean. Scientists and mari...

The Triplewart Seadevil (Cryptopsaras couesii) is a deep-sea fish belonging to the Ceratiidae family. It’s notable for its bioluminescent appendages and unique parasitic mating system. Male seadevils permanently attach themselves to females, integrating their circulatory systems. This adaptation all...

Stauroteuthis syrtensis is a deep-sea cirrate octopus found in the North Atlantic, where it inhabits dark waters far below the surface. Structures associated with its suckers have developed into photophores that produce blue-green light, an unusual adaptation among octopuses. The light may help attr...

Vampyroteuthis infernalis, commonly called the vampire squid, is a deep-sea cephalopod distinguished by its dark red coloration and ability to tolerate extremely low oxygen levels. This relic species, belonging to the Vampyromorpha order, was initially described in 1903. It’s notable for its unique...

Deepstaria enigmatica is a deep-sea jellyfish recognized by its unusually thin, broad bell, which can fold into a baglike form around prey.
