A molluscivore is a carnivorous animal that specialises in feeding on molluscs such as gastropods, bivalves, brachiopods and cephalopods.Known molluscivores include numerous predatory (and often cannibalistic) molluscs, (e.g. octopuses, murexes, decollate snails and oyster drills), arthropods such as crabs and firefly larvae, and vertebrates such as fish, birds and mammals.

Triton's trumpet, a very large gastropod mollusk, is a known predator of Acanthaster in some parts of the starfish's range. The Triton has been described as tearing the starfish to pieces with its file-like radula. [39] The small painted shrimp Hymenocera picta, a general predator of starfish, has been found to prey on A. planci at some ...
Georg Eberhard Rumpf found few starfish being used for food in the Indonesian archipelago, other than as bait in fish traps, but on the island of "Huamobel" the people cut them up, squeeze out the "black blood" and cook them with sour tamarind leaves; after resting the pieces for a day or two, they remove the outer skin and cook them in coconut ...
The relatively large size of fairy shrimp, together with their slow means of locomotion, makes them an easy target for predatory fish and waterfowl. [10] This has led to their distribution being restricted to environments with fewer predators, such as vernal pools , salt lakes and lakes at high altitudes or latitudes. [ 10 ]
Hymenocera picta, commonly known as the harlequin shrimp, is a species of saltwater shrimp found at coral reefs in the tropical Indian and Pacific Oceans.It is usually considered the only species in the genus Hymenocera, [1] [2] but some split it into two species: H. picta from the central and east Pacific, where the spots are deep pinkish-purple with a yellow edge, and H. elegans from the ...
A food web is network of food chains, and as such can be represented graphically and analysed using techniques from network theory. [1] [2] Classic food web for grey seals in the Baltic Sea containing several typical marine food chains [3] The fourth trophic level consists of predatory fish, marine mammals and seabirds that consume forage fish.
The species Mysidium integrum has a mutualistic relationship with longfin damselfish, the shrimp providing nutrients for the algae farms the fish feed on and the fish providing protection from predators. [7] [8] The majority of Mysida are omnivores, feeding on algae, detritus, and zooplankton.
The genus Linckia, as is true of other species of starfish, is recognized by scientists as being possessed of remarkable regenerative capabilities, and endowed with powers of defensive autotomy against predators: [citation needed] Although not yet documented, L. laevigata may be able to reproduce asexually, as does the related species Linckia ...
