Diseases of crayfish: A review
Journal of Invertebrate Pathology, 2011A systematic review of parasites, pathogens and commensals of freshwater crayfish has been conducted. All major groups of disease causing agents have been covered including viruses, bacteria, fungi, protistans and metazoans. Most agents tend to cause limited problems for crayfish. Exceptions to this include fungi, bacteria and viruses. However, in many

I am an 8th-grade student at Westland Middle School in Bethesda, Maryland. I read with interest the article “Neurobiology: Social status sculpts activity of crayfish neurons” by Marcia Barinaga (Research News, [19 Jan., p. 290][1]), which discussed the report “The effect of social experience on serotonergic modulation of the escape circuit of crayfish”

To the Editor.— As any of the gourmets among your readers will have recognized, the specimen on the cover of the May 2 issue (237:cover, 1912, 1977) would never have graced the dinner table of any self-respecting Yankee from Maine. That animal is not a lobster, but rather a crayfish. The American lobster ( Homarus americanus ) is readily identified by

Many synaptic studies have utilized the experimental advantages of the Arthropod NMJ and the most prominent preparations have been the crayfish and Drosophila larval NMJs. Early cellular studies in the crayfish established the framework for later molecular studies in Drosophila.

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.

Carotenoids of Cavernicolous Crayfish
Science, 1964Small amounts of β-carotene and lutein were found in Orconectes pellucidus pellucidus . Cambarus bartonii tenebrosus from the same cave contained much less carotenoid than surface crayfish. Astaxanthin, the principal carotenoid of most Crustacea, was absent from O. p. pellucidus

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.

An Electric Sense in Crayfish?
The Biological Bulletin, 2007A variety of aquatic vertebrates, including teleost and non-teleost fish, amphibians, and monotreme mammals, are sensitive to low-frequency electric signals with thresholds of low nanovolts per centimeter to high microvolts per centimeter, have specialized detectors for these signals, and use electroreception to locate food or orient in their ...
