Forage fish are the food that sustains larger predators above them in the ocean food chain. The superabundance they present in their schools make them ideal food sources for top predator fish such as tuna, striped bass, cod, salmon, barracuda and swordfish, as well as sharks, whales, dolphins, porpoises, seals, sea lions, and seabirds.

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.
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 ...
Scotoplanes (and all deep-sea holothurians) are deposit feeders and obtain food by extracting organic particles from deep-sea mud. Scotoplanes globosa has been observed to demonstrate strong preferences for rich, organic food that has freshly fallen from the ocean's surface [7] and uses olfaction to locate preferred food sources such as whale ...
Ram feeding and suction feeding are on opposite sides of the feeding spectrum, where extreme ram feeding is when a predator swims over an immobile prey item with open jaws to engulf the prey. Extreme suction feeding is demonstrated by sit-and-wait predators that rely on rapid depression of the jaws to capture prey (e.g., frogfish, Antennariidae ).
Forage fish occupy middle levels in the food web, serving as a dominant prey to higher level fish, seabirds and mammals. [28] Predator fish; Ground fish; Other marine vertebrates. In 2010, researchers found whales carry nutrients from the depths of the ocean back to the surface using a process they called the whale pump. [29]
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.
For larger, heavier-shelled prey, otters will sometimes exhibit tool-use behavior, breaking open sea urchins and mussels with a false stone used as an anvil. Sea otters can also bite sea urchins and mussels open using their strong jaws and teeth. Adults can crush most of their food items but youngsters have not yet developed powerful enough jaws.
