Crustaceans have long been used for peptide research. For example, the process of neurosecretion was first formally demonstrated in the crustacean X-organ-sinus gland system, and the first fully characterized invertebrate neuropeptide was from a shrimp.

This chapter provides are view of recent progress in the elucidation of innate immune mechanisms in crustaceans. Mainly due to the importance of crustacean aquaculture interest in this field is large and the subject for extensive research efforts. Here, we provide detailed data on the molecular characterisation of lectins, antiviral reactions, hemocyte

The Circadian System of Crustaceans
Chronobiology International, 1993Crustaceans exhibit a variety of overt circadian rhythms. Observations on intact animals suggest the existence of more than one circadian pacemaker in the nervous system. Ablation experiments so far have been inconclusive in pin-pointing the location of putative pacemakers.

Thermal behaviour of crustaceans
Biological Reviews, 2006ABSTRACTSpecific thermoreceptors or putative multimodal thermoreceptors are not known in Crustacea. However, behavioural studies on thermal avoidance and preference and on the effects of temperature on motor activity indicate that the thermosensitivity of crustaceans may be in the range 0.2–2°C. Work on planktonic crustaceans suggests that they respond

Crustaceans play a considerable ecological role in both marine and freshwater trophic networks. Although the vast majority of crustaceans are theoretically edible by humans, only rather large and common species are generally collected. As a matter of fact, decapods (crabs, shrimps, lobsters) constitute the vast majority of crustaceans eaten by humans ...

Neurohæmal Organs in Crustaceans
Nature, 1953A NUMBER of structures of nervous origin in the higher Crustacea have recently been described under a variety of names, although they show a unity of structure and possibly of function. We wish to propose, tentatively, a common name to denote organs of this type in crustaceans, in order to avoid a needless multiplicity of names for organs which have ...

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.

Nature, 1910 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

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,
