Praya dubia is an active swimmer that attracts its prey with bright blue bioluminescent light. [15] When it finds itself in a region abundant with food, it holds its position and deploys a curtain of tentacles covered with nematocysts which produce a powerful, toxic sting that can paralyze or kill prey that happen to bump into it.

Stygiomedusa gigantea, commonly known as the giant phantom jelly, is the only species in the monotypic genus of deep sea jellyfish, Stygiomedusa. It is in the Ulmaridae family . [ 2 ] With only around 110 sightings in 110 years, it is a jellyfish that is rarely seen, but believed to be widespread throughout the world, with the exception of the ...
It is apparently the top predator along certain stretches of the Mariana Trench, feeding on tiny crustaceans in a deep-water habitat with few larger predators. [4] Pseudoliparis swirei are abundant in their deep-sea habitat and lay relatively large eggs that are almost 1 cm (0.4 in) in diameter. [2]
a Beroe ovata, b unidentified cydippid, c "Tortugas red" cydippid, d Bathocyroe fosteri, e Mnemiopsis leidyi, and f Ocyropsis sp. [17]. Among animal phyla, the ctenophores are more complex than sponges, about as complex as cnidarians (jellyfish, sea anemones, etc.), and less complex than bilaterians (which include almost all other animals).
Consequently, the predators and prey will be locked in an evolutionary arms race, each looking to gain the upper hand on the other. The presence of fish predators play a large role in the size, shape and swimming performance of the Lithobates clamitans tadpoles. The presence of these predators in their habitat causes the tadpoles to develop ...
The predatory tunicate (Megalodicopia hians), also known as the ghostfish, [2] is a species of tunicate which lives anchored along deep-sea canyon walls and the seafloor.It is unique among other tunicates in that rather than being a filter feeder, it has adapted to life as an ambush predator.
This is thought to help the animals move to new feeding grounds and avoid predators. [6] The sea cucumber ranges in size from 11 to 25 centimeters (4.3 to 9.8 in). [7] Its most distinct feature is its coloring, which is dictated by size: small enypniastes are a bright pink, and larger individuals are a more reddish-brown color.
Tunicata, also known as sea squirts or sea pork, are filter feeders attached to rocks or similarly suitable surfaces on the ocean floor; Some flatworms of the classes Turbellaria and Monogenea; Xenoturbella, a genus of bilaterian animals that contains only two marine worm-like species;
