Sun jellyfish, scientific name: voragonema pedunculata, body length 4 cm in diameter, water depth 500 ~ 3500 meters. Jellyfish are generally believed to be kept away from reefs with sharp rocks, with the exception of sun jellyfish. Because there are small sticky tentacles, often attached to the rock wall; other tentacles will extend outwards, this is to catch prey carried away by the current.
The naked sea butterfly, or clione in English, is a mollusk living in the polar oceans, whose scientific name means "nude" in Greek. Also known as sea angels.
Their swimming posture is both beautiful and ghostly. The sea angel is a hermaphrodite that feeds on another closely related mollusk, the sea butterfly (the suborder thecosomata). Seeing the sea angels swinging in the water, it is not difficult to understand the origin of their names. In addition to its transparent "wings", sea angels have pointed, horn-like protrusions.
Carnivorous rucksacks, a tail cord, megalodicopia hians, and humans are a phylum. Fixed at the bottom of the sea, something swims in and eats it... Same as the piranha in Super Mario. Notice the hole in the top of the head, which is its outlet hole, and the anus grows inside.
The piglet octopus, scientifically known as "helicocranchia pfefferi", is the size of a large orange, usually living in an ocean area 100 meters deep, and it is a slow-moving squid. This pig-like squid has curly hair-like tentacles. A special pigmentation on its body forms a pattern of grinning faces under its eyes. Another feature of it is that there is a luminous organ behind the eye that produces light that makes it look like a glass ball.
Ānkāng, commonly known as jiébā fish, haledge, sea toad, anglerfish, etc., generally live in tropical and subtropical deep-sea waters. It is a bony fish, lophiiformes, and a cosmopod in the family Cyprinidae, and is a world fish found in the Atlantic, Pacific and Indian Oceans.
Above the head of the trout there is a fleshy protrusion, shaped like a small lantern, which is formed by the gradual upward extension of the first dorsal fin of the trout. The reason why the small lantern emits light is because it has glandular cells in the lantern that can secrete photons, which emit light by slow chemical oxidation with oxygen under the catalysis of photonase. Many fish in the deep sea have phototropism, so the small lantern becomes a weapon for the trout to lure food.
