The potency of marine snakes is matched by that of some cone shells. Many octopuses have also faced the problem of shelled prey. Omnivorous fish consume microalgae together with crustaceans for that they ought to go hunting. Sponges: The fish of omnivorous category, like Angelfish, eat sponges.

Having located its bivalve prey, the starfish envelopes it and gradually exerts intense pressure in an attempt to gain access, applying an incredible force at the bivalve's hinge.

The group includes 95% of all animal species - all animals except those in the Chordate subphylum Vertebrata (fish, reptiles, amphibians, birds, and … Aquatic vertebrates and invertebrates used for biological control include such groups as fish for biological aquatic weed and arthropod control and Turbellaria and Coelenterata for arthropod control. Here is where the food web starts getting complicated and interrelated, because when predatory fish are young and small, they can feed on zooplankton and aquatic insects, and when they are adults, they will feed on minnows and fish. The “cigarette snail” is so-called because an attack by this animal is thought to leave little time for anything other than a final smoke! The demersal fish and invertebrates consume organic matter that does arrive, break it down and recycle it. The majority of fish are carnivorous, whereas some of them are entirely herbivorous. Also, because fish eat water boatmen, fly-fishers sometimes craft lures replicating the insects, then simulate their jerky swimming pattern in order the catch fish—and have a lot of fun in the process!
