Polarisation Vision of Crustaceans
, 2014 The photoreceptor design of crustaceans, often containing regular arrays of intrinsically polarisation-sensitive microvilli, has had a profound influence on the visual biology of this subphylum. The land-based arthropods (insects and arachnids) also construct photoreceptors from ordered microvilli; however while in many species polarisation sensitivity

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.

Temporal resolution in mesopelagic crustaceans
Philosophical Transactions of the Royal Society B: Biological Sciences, 2000 Mesopelagic crustaceans occupy a dim-light environment that is similar to that of nocturnal insects. In a light-limited environment, the requirement for greater sensitivity may result in slower photoreceptor transduction and increased summation time ...

Abstract The crustaceans (Phylum Crustacea) exhibit a great diversity of structure, adaptation, and development. Freshwater and terrestrial species are common, but the majority of species are marine. Crustaceans occur in all marine habitats, from the supralittoral zone to the abyss; additionally, most holoplanktonic animals belong to the

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

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

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.
