Animals are generallymotile.They have the capacity to move at will. They can spontaneously and actively move by metabolically utilizing energy (e.g.ATP) during the process and with the aid of muscles and locomotory structures (e.g. arms, legs, wings, fins, tails, etc.). Animal locomotion ...
Octopuses prey on a variety of animals, but the most important prey for many species arebivalves– mollusks with two-part shells, and crustaceans such ascrabsandcrayfish. Octopuses either prize open the shells of their shellfish prey, or create small holes in the shells through which they inje...

Nematodes, also calledroundworms, are non-segmented worms that are found in thephylum Nematoda. They are members of the group Ecdysozoa, which also includes insects, arachnids, and crustaceans. These animals are all able to shed their cuticles. Nematodes are ubiquitous, which means that they ...
crustaceans and some plant material. While young, platypuses have teeth. But teeth are absent from the adults, who instead use a pair of horny plates located in the jaws to crush and chew food. Adult male platypuses have grooved spurs, attached to venom glands in their legs, that are likel...

Over time, they metamorphose into molluscs, corals, fishes, insects, echinoderms, and crustaceans. Holoplankton: Zooplanktons that remain planktonic throughout their lives. Pteropods, larvaceans, copepods, chaetognaths, and siphonophores are examples of these organisms. Distribution of Zooplankton ...
Flukes or trematodes are parasitic flatworms from the class Trematoda. They may be internal or external parasites of vertebrates including fish,crustaceans,mollusks, and humans. Flukes have flat bodies with suckers and spines that they use to attach to and feed off of their host. Like other fla...
