are organisms belonging to the kingdomAnimaliaand the phylum Arthropoda. They are a very diverse group of animals that includes but is far from limited to insects, crustaceans, spiders, scorpions, and centipedes. Arthropods make up the largest phylum in the world, with more numbers and species ...
Different natural products can be used to create edible packaging, but the most effective and widely used is chitosan, a sugar made from the chitin shells of crustaceans. This makes chitosan one of the most plentiful biopolymers – and edible packaging a much greener altern...
However, the largest mix of marine producers (and their consumers) exist in warmer ocean waters. Fish and invertebrates are ectotherms that must rely on the temperature of their environment to maintain a constant body temperature. Organisms that exist in frigid waters, such as near the North and...
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...
Among decapod crustaceans, there is evidence for adult neurogenesis in basal species of the Dendrobranchiata, as well as in more recent terrestrial, marine and fresh-water species. The widespread nature of this phenomenon in decapod species may relate to the importance of the adult-born neurons,...
the dominant invertebrates are bivalve mollusks and crustaceans. As for the dominant vertebrates, fish dominated the aquatic habitats. Major predators include elasmobranchs in the seas and Xenacanthida in freshwater. Arthropods on land continued to evolve. Some of them grew intogiants. For example, ...
are one of the most diverse ecosystems on earth. As such, they are referred to as therainforests of the sea. Most of them are found at shallow depths in tropical waters. Some of the species that inhabit the reefs are mollusks, worms, crustaceans, echinoderms, sponges, tunicates, and fish...
* Given that trilobites were largely marine animals, their diet may have largely consisted of dead or decaying matter as well as marine plankton and some crustaceans.Subphylum ChelicerataSubphylum Chelicerata is composed of such marine and terrestrial animals as scorpions, horseshoe crabs, ticks, ...
