Abstract 1. 1. Sterol compositions of 14 species of Crustacea were determined by high-resolution gas-liquid chromatography (GLC). 2. 2. Cholesterol was the major sterol in all species and comprised from 99 to 100 per cent of the total sterol in the euphausid, Nyctiphanes norvegica , 4 species of the suborder Macrura, and i species of the ...

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.

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 ...

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

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.

Significant developmental studies in the arthropod phylum have been largely confined to insects and this chapter reflects this situation. We have deliberately ignored myriapods and arachnids and the crustaceans receive only brief attention. Many insects are easy to keep and they breed quickly in captivity.

The class Ostracoda is made up of small crustaceans, with a shell size generally ranging from 0.2 to 30 mm, living in a wide variety of aquatic environment, from deep-sea waters to the proximity of hydrothermal springs. A small number of species has been recorded in damp terrestrial environments. The majority of the taxa have a wholly benthic lifestyle,

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 ...
