Scotoplanes globosa, commonly known as the sea pig, is a species of sea cucumber that lives in the deep sea. [1] It was first described by Hjalmar Théel , a Swedish scientist. Scotoplanes globosa , along with numerous other sea cucumbers were discovered by Théel during an expedition on HMS Challenger between the years of 1873-1876.
Forage fish, also called prey fish or bait fish, are small pelagic fish that feed on planktons (i.e. planktivores) and other small aquatic organisms (e.g. krill). They are in turn preyed upon by various predators including larger fish, seabirds and marine mammals , this making them keystone species in their aquatic ecosystems .
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 ...
Sea pigs are also known to host different parasitic invertebrates, including gastropods (snails) and small tanaid crustaceans. [ 9 ] A living Scotoplanes from Monterey Bay with a juvenile Neolithodes diomedae king crab sheltering beneath it at a depth of approx. 1260 metres.
Orthopristis chrysoptera, the pigfish, hogfish, piggy perch, redmouth grunt or sailor's choice, is a species of marine ray-finned fish, a grunt belonging to the family Haemulidae. It is found in the western Atlantic Ocean. This name derives from the grunting or chattering noise these fish make by rubbing their pharyngeal teeth together.

The tentacles are sensitive and the anemone knows when prey is present. When a creature swims near, such as a small fish or crustacean, the anemone quickly grabs it and closes its tentacles around it.
The sea otters eat while floating on their backs, using their forepaws to tear food apart and bring to their mouths. [64] [65] Marine otters mainly feed on crustaceans and fish. [66] Pinnipeds mostly feed on fish and cephalopods, followed by crustaceans and bivalves, and then zooplankton and warm-blooded prey (like sea birds).
