ABSTRACTAn analysis of swimming in living crustaceans is presented in order to elucidate the range of ways this function has been achieved, and to reveal the principles which constrain it. The study focuses onGnathophausia ingens, a primitive, bathypelagic malacostracan that swims with thoracic exopods and pleopods.

The Crustacea have been called the “water-breathing insects of the sea” (Schmitt, 1965). Although they have invaded both freshwater and terrestrial habitats, this description gives a reasonable intuitive feeling for many of the general behavioral and morphological characteristics of the class.

Crustaceans show an extraordinary diversity for their ways of life and their diets. A large number of habitats have been occupied by crustaceans; however, they are basically aquatic and mainly marine. While crustaceans occupy diverse aquatic environments, that is, marine and both riverine and lacustrine fresh waters, there are also many paralittoral or

Hypo-osmoregulation in Crustacea
Comparative Biochemistry and Physiology, 19671. 1. Use of alcohol 110Ag established water-drinking of 6-7 μl. g-1 hr-1 for three species of marine Crustacea, but in iso-osmotic Metapenaeus bennettae some oral intake still occurred; anal uptake was constant and independent of salinity. 2. 2. Measurements of Na+, Cl-, 22Na, 36Cl indicated that the anterior diverticula of the mid-gut, and not the ...

Deoxyribonucleic acids of crustacea
Journal of Molecular Biology, 1964A study of the deoxyribonucleic acids present in the testes of species from nine genera of crustaceans, representing the sub-groups Malacostraca and Cirripedia, has been carried out using the techniques of density-gradient centrifugation in cesium chloride and thermal denaturation.

Cirripedes are crustaceans, where the adult forms are so structurally and biologically diverse that it would be impossible to argue from these forms alone that they belong to this group of organisms (Fig. 5.1; Anderson 1994). Yet, cirripede monophyly is assured by a similar and unique ontogeny and in recent years also by robust molecular evidence ...
