PenBase provides comprehensive information about penaeidin properties, function, diversity and nomenclature. PenBase contains a Database section that lists all known penaeidins by subgroup or shrimp species. (...) Antimicrobial peptides are major components of innate immunity that have been conserved in evolution and found in different phyla of the plant and animal kingdom. Antimicrobial peptides are often small cationic molecules widely distributed in the whole living kingdom where they participate to host defence reactions against invading microorganisms. They are known to be involved in the innate immune response of vertebrate, invertebrate and plant species, and they are thought to be essential in organisms which lack adaptive immunity. Penaeidins are members of a family of antimicrobial peptides, originally isolated from the shrimp Litopenaeus vannamei, which present both Gram-positive antibacterial and antifungal activities (Destoumieux et al, 1997). Penaeidins appear to be a family of antimicrobial peptides ubiquitous among penaeid shrimps where they are major actors of the immune response (Bachère et al., 2004). ...

The list of isopod crustaceans has been compiled from a variety of sources, including numerous individual papers and monographic works, and the collections and catalogues of the National Museum of Natural History, Smithsonian Institution. (...) Having compiled a list of about 5,300 marine and freshwater isopod crustaceans of the world (Kensley and Schotte, 1995), we thought that the addition of the terrestrial isopods to the list would create a more valuable taxonomic and biogeographic tool. (...) ... [Information of the supplier, modified]
What is a copepod? These small aquatic crustaceans are very diverse and are the most numerous metazoans in the water community. Copepod habitats range from fresh water to hypersaline conditions, from subterranean caves to water collected in bromeliad leaves or leaf litter on the ground and from streams, rivers, and lakes to the sediment layer in the open ocean. Ecologically the planktonic copepods are important links in the aquatic food chain linking microscopic algal cells to juvenile fish to whales. Copepods also have the potential to act as control mechanisms for malaria by consuming mosquito larvae, and contrariwise are intermediate hosts of many human and animal parasites. Although they belong to a separate class of crustaceans, Branchiura (commonly referred to as fish lice) are dealt with here along with the Copepoda, since many copepod researchers also study these external parasites of fish and amphibians. Together the Copepoda and Bracnhiura comprise over 250 described families; 2,600 genera and over 21,000 described species (both valid and invalid, including senior and junior synonyms). The bibliographic database was developed and is maintained by staff of the C.B. Wilson Copepod library, and contains all the known literature for copepods and branchiurans. At present over 53,700 bibliographic entries on copepods are in the database. ... [Information of the supplier, modified]
This is a database of systematic literature on the Decapoda, compiled by the Assembling the Tree of Life: Decapoda project. You can search references online, or download the entire library as an Endnote-compatible reference library. In many cases, we are able to make the full text of the papers available as PDF files. The online references search will also give information on PDF availability. ... [Information of the supplier]
This site is dedicated to zooplankton of the Arctic ocean and adjacent seas. This is a diverse group of animals, which includes over 300 species and 9 phyla: cnidarians, ctenophores, crustaceans, molluscs, chaetognaths, rotifers, annelids, nemertines and chordates (i.e. tunicates). This project is done with the support of the Encyclopedia of Life Rubenstein fellows program and in partnership with the Arctic Ocean Diversity project. ... [Information of the supplier]
