Blackened by the fire, squid and crustacean were eaten without condiment, the tentacles being devoured as one eats celery. It served as both nest and nourishment for myriads of crustaceans and mollusks, for crabs and cuttlefish. The whales subsist entirely upon these small crustaceans. They also carry the spawn of fishes and small crustaceans among their feathers into new waters, and feed upon the countless seeds of weeds that are scattered broadcast over the face of the earth. crustacean | American Dictionarycrustacean noun[ C ] us/krʌˈsteɪ·ʃən/ any of various types of animals that live in water and have a hard outer shell and many legs: Crabs, lobsters, and shrimps are crustaceans. Examples of crustaceancrustacean Do eel parasites reflect the local crustacean community? The parasite species with indirect life cycles recorded in the river have mostly benthic molluscs and crustaceans as intermediate hosts. It has a scattered phylogenetic distribution, but it is common and has persisted for long periods of evolutionary time in branchiopod crustaceans. Benthic crustaceans are also important intermediate hosts of several helminth parasites. They were examined for helminth and crustacean parasites only by standard methods, from all organs except the blood system. A key area is the evidence for insects being closely related to crustaceans. Such findings diverge from what was observed in the present study, where crustaceans were present in approximately 20% of scat samples analysed for each species. Other specializations may not have evolved in parasites of benthic crustaceans, though preference of single species usually changes from locality to locality. Impact of a novel, feminising microsporidium on its crustacean host. Therefore, changes of eel parasite diversity can be correlated with the appearance of invading crustacean species (neozoans). A large portion of this overlap is due to the prominence of crustaceans in fish diets. Many of these projects aim to produce high-tech products modelled on insects, crustaceans and marine wildlife. Many types of seafood, especially oysters, shrimp and the other crustaceans are often eaten raw or undercooked. Other crustaceans also feel the effects of parasites. These studies illustrate the complex web of parasite transmission that occurs through the crustaceans alone in benthic communities. These examples are from corpora and from sources on the web.
