Crayfish immunity – Recent findings
Developmental & Comparative Immunology, 2018Freshwater crayfish is an important commodity as well as a successful model for studies on crustacean immunity. Due to the ease with which they are kept and the available methods for hemocyte separation and culture they have proven to be very useful.

ABSTRACT Curve walking of crayfish Astacus leptodactylus was investigated by exploiting their optomotor response. The animal walked while spatially fixed on a motor-driven treadmill and turning behaviour was induced by an optical stimulus, a pattern consisting of vertical stripes moving in a horizontal direction.

Architectonics of crayfish ganglia
Microscopy Research and Technique, 2003AbstractThe central nervous system of crayfish consists of a chain of segmental ganglia that are linked by cables of intersegmental axons. Each ganglion contains a highly‐ordered core of longitudinal tracts, vertical tracts, commissures, and synaptic neuropils.

Sleep, a complex phenomenon with an unknown function, is present in a wide range of animals, both vertebrates and invertebrates. Sleep definitions typically include at least two of three main criteria: behavioral, brain electrical activity, and the activation of certain genes.

Crayfish have been in demand as desirable food items around the globe for centuries, and entrepreneurs have capitalized on this demand by developing and applying aquaculture principals for the intentional culture of this freshwater crustacean. The current state of the art has advanced within the last half century and is centered on a handful of species,

Signal crayfish as vectors in crayfish plague in Britain
Aquaculture, 1990Abstract An outbreak of crayfish plague (caused by the fungus Aphanomyces astaci) is described in white-clawed crayfish, Austopotamobius pallipes, in enclosed pond culture in an area of England from which no disease outbreaks have yet been reported.

Crayfish are decapod crustaceans that use different forms of escape to flee from different types of predatory attacks. Lateral and Medial Giant escapes are released by giant interneurons of the same name in response to sudden, sharp attacks from the rear and front of the animal, respectively.

Crayfish eye extracts contain two visual pigments resembling in spectrum vertebrate rhodopsin and iodopsin. In these crayfish, as in primates, the “iodopsin” appears to be the red sensitive pigment of colour vision.
