Some cool and unusual living organisms in the depth of the sea.
Modern research has shown that, despite the pitch-blackness of the water, the freezing cold, and the crushing pressure, some amazing and bizarre creatures have adapted to life in the depths of the sea.

This Russell lionfish’s bright colors act as a warning. Hidden behind its fin, the fish has spines that can inject a deadly poison into attacker. The lionfish is also known as the Turkey Fish or Dragon Fish. They are notable for their extremely long and separated spines, and have a generally striped appearance, red, brown, orange, yellow, black, maroon, or white.
Vampire Squid (Vampyroteuthis infernalis)
Literally means “vampire squid from hell,” is a small, deep-sea cirrate cephalopod found throughout the temperate and tropical oceans of the world. Unique retractile sensory filaments justify the Vampire Squid’s placement in its own order. It shares similarities with both squid and octopuses. As a phylogenetic relict it is the only known surviving member of its order.
Japanese Spider Crab (Macrocheira kaempferi)
This is the largest known arthropod; fully grown it can reach a leg span of almost 4 m (13 ft), a body size of up to 37 cm (15 inches) and a weight of up to 20 kg (44 lb). The crab’s natural habitat is on the bottom of the Pacific Ocean (some 300 to 400 m deep) around Japan, where it feeds on dead animals and shellfish. It is believed to have a life expectancy of up to 100 years
The Antarctic icefish belong to the perciform and are the largely endemic, dominant fish taxa in the cold continental shelf waters surrounding Antarctica. The majority of Notothenioids live at seawater temperatures between of -2°C and 4°C. It is possible to have seawater temperatures below the freezing point of fresh water (0°C) because dissolved salts lower the freezing point of a solution in a colligate manner. Antarctic icefish has no red blood cells. Direct absorption from seawater affords sufficient oxygen for its slow metabolism.
Lion’s Mane Jellyfish (Cyanea capillata)
The lion’s mane jellyfish gets its name from its thick mane-like mass tentacles and its tawny color. The stinging tentacles may be up to 33 ft or 10 m long. It is the largest known species of jellyfish. The Arctic Lion’s mane jellyfish is one of the longest known animals; the largest recorded specimen had a bell (body) with a diameter of 2.3 m (7 feet 6 inches) and the tentacles reached 36.5 m (120 feet). It was found washed up on the shore of Massachusetts Bay in 1870.
