YESTERDAY my assistant, Mr. G. Pyman, found several Cheirocephalus diaphanus swimming in a flooded ditch on Eton Wick Common. The sunlight shining on the beautiful green bodies of the males made a very striking effect. We were able to catch about twenty specimens of both sexes. I had never seen this phyllopod alive before, and, so far as I know, it has

Glycolytic activity in crustaceans
Comparative Biochemistry and Physiology, 1970Abstract 1. 1. The specific activities of the glycolytic enzymes in crustacean muscle are comparable to those found in rat liver, except that the ratio of glyceraldehyde-3-dehydrogenase to lactic dehydrogenase was greater in crustacean muscle (≅3 : 1) than in rat liver (1 : 4·5) or rat muscle (1 : 1·45). 2. 2.

Crustaceans and the "Cambrian Explosion"
Science, 2001We noted with interest the report by Siveter et al . ([1][1]) of new phosphatocopid specimens showing soft-part preservation from the Lower Cambrian Comley Limestones, but we question some of the interpretations both in the report and in the accompanying Perspective by Fortey ([2][2]). First,

The crustacean zooplankton of these large lochs is described from a series of vertical net hauls taken there during 1977–78. A total of 11 planktonic species of Crustacea was found — six of them common to all the lochs. There were sufficient differences in the occurrence of the other five species for it to be possible to identify the community of each ...

Publisher Summary Crustaceans are an unusually diverse and widespread group that includes marine species of major economic importance—such as lobsters, shrimps, and crabs—as well as isopods, copepods, barnacles, and euphausiids. Crustaceans are aquatic arthropods that typically respire by gills and possess two pairs of antennae, three pairs of primary

Antimicrobial Proteins in Crustaceans
2001Crustacean shellfish along with their molluscan relatives have been an important source of food for humans for much of history. Shells of marine invertebrates have been found littered amongst the remains of primitive cooking utensils uncovered during twentieth century excavations of the neolithic settlements at Skara Brae on the Isle of Orkney, north ...

This chapter deals with the chronology, systematics, and symbolism of artistic representations of crustaceans. The earliest known presence of crustaceans in art can be traced back to ancient Egypt and Assyria. The oldest figure of a crustacean known at the time of this writing seems to concern spiny lobsters in an Egyptian painting of the 18th Dynasty.
