Decapoda - Wikipedia, the free encyclopedia The decapods or Decapoda are an order of crustaceans within the class Malacostraca, including many familiar groups, such as crabs, lobsters, prawns and shrimps, but also some families that are less well known. As their name implies, all decapods have ten legs; these are the last five of the eight pairs of thoracic appendages characteristic of crustaceans. Further appendages are found on the abdomen, with each segment capable of carrying a pair of biramous pleopods, the last of which form part of the tail fan (together with the telson) and are called uropods. en.wikipedia.org /wiki/Decapoda   (277 words)

Last check: 2007-11-03) This group of decapods is a good example of a living fossil, or a lazarus taxon, since until their discovery in the 1970s, the group was considered to have become extinct in the Eocene. The anatomy of the lobster includes the cephalothorax which is the head fused with the thorax, both of which are covered by the carapace, and the abdomen. - Brachyura Pleocyemata is a sub-order of decapod crustaceans, erected by Martin Burkenroad in 1963. schriftzeichenlogogramm.de.wikimiki.net /en/Decapod   (9776 words)

Anatomy A decapods body is composed of a series of hard segments called somites. Decapods have a fast growth rate and need to moult their exoskeleton to grow. A soft new shell is continually grown under their existing exoskeleton and as the moult draws near a hormone is released from sacks in the eye stalks. www.shrimpcrabsandcrayfish.co.uk /Anatomy.htm   (1318 words)

WikiMiki.net - Pleopod   (Site not responding. Last check: 2007-11-03) Long-bodied decapod crustaceans such as shrimps, prawns, crayfish and lobsters are alone in having reflecting superposition eyes, which also has a transparent gap but uses corner mirrors instead of lenses. In anatomy, the anus (from Latin ānus "ring, anus") is the external opening of the rectum. Carcinization is believed to have occurred in a number of groups of decapod crustaceans, most notably king crabs which most scientists believe evolved from hermit crab ancestors (there is still some debate over this point). 1510.ro.wikimiki.net /en/pleopod   (4292 words)

The anatomy of crayfish may be found in the article "Decapod anatomy". The name "crayfish" does not derive from the word "fish", but rather from the Old French word escrevisse (Modern French écrevisse) meaning "crevice" and referring to the habitat of the animal. www.yourart.com /research/encyclopedia.cgi?subject=/crayfish   (1157 words)

Everything about Crab   (Site not responding. Last check: 2007-11-03) The term carapace refers to a dorsal section of an exoskeleton or shell, in a number of animal groups. This article is based on an entry from the 1918 edition of Gray's Anatomy, which is in the public domain. Crab lice (singular, louse), scientific name Phthirus pubis and commonly called "crabs" due to their resemblence to the crab, are one of three kinds of human lice in the large group of lice families, the others being head lice and body lice, which live in clothing. al.pt.wikimiki.org /en/crab   (11895 words)

Amazon.ca: Microscopic Anatomy of Invertebrates, Volume 10, Decapod Crustacea: Books   (Site not responding. Last check: 2007-11-03) The 15 individual volumes are arranged phylogenetically, beginning with the protozoa, defined herein as the motile protists, and concluding with the invertebrate members of the phylum Chordata. Although gross and external anatomy are discussed in some detail, the emphasis of this work is consistently on functional invertebrate anatomy, particularly at the ultrastructural level. It does not remain limited to fundamental descriptions of anatomical structure but rather goes beyond that level to offer a compelling view of microscopic anatomy that relates structure to function in various organisms. www.amazon.ca /exec/obidos/ASIN/0471561177   (306 words)

Daphnia Genomics Consortium - The DGC Organization Several fundamental observations about olfaction were made first using lobsters, largely due to advantages that stem from their anatomy and a wealth of background knowledge. Molting in decapod crustaceans is controlled by the X-organ/sinus gland complex, a neurosecretory center in the eyestalks. The principles of molecular recognition at the genomic and proteomic levels were developed for single gene analysis, and data analysis of global expression profiling requires knowledge of gene families and products. daphnia.cgb.indiana.edu /people/events/12   (2463 words)
