TLDR
An increase in the rate of antennule flicking and gill bailing upon presentation of sea water solutions of a freeze-dried clam extract indicated detection of sapid substances by the blue crab, Callinectes sapidus.Abstract:
1. An increase in the rate of antennule flicking and gill bailing upon presentation of sea water solutions of a freeze-dried clam extract indicated detection of sapid substances by the blue crab, Callinectes sapidus.2. The threshold concentration at which crabs detected the sapid solution was 10-15 g/liter. Feeding behaviors were released at higher concentrations, 10-1 to 10-2 g/liter.3. Food deprivation for six days lowered the threshold for feeding behaviors but did not affect the detection threshold.read more

Life and Death in Moving Fluids: Hydrodynamic Effects on Chemosensory-Mediated Predation
TL;DR: Investigation of predatory success and search strategies of blue crabs foraging in controlled hydrodynamic environments generated in a flume indicates that mechanisms governing the physical transport of odor signals can have profound influences, not only on the development of sensory and behavioral mechanisms, but also on biotic interactions such as predation.

Chemical signaling processes in the marine environment
TL;DR: There are now vast new opportunities for determining how organisms respond to chemical signals and employ chemical defenses under environmentally realistic conditions, and integrating findings within a larger ecological and evolutionary framework should lead to improved understanding of natural physicochemical phenomena that constrain biological responses at the individual, population, and community levels of organization.
Synopsis of biological data on the blue crab, callinectes sapidus Rathbun
TL;DR: This synopsis reviews taxonomy, morphology, distribution, life history, commercial hard and soft shell crab fisheries, physiology, diseases, ecology, laboratory culture methodology, and influences of environmental pollutants on the blue crab, Callinecles sapidus.

Function of chemoreceptor organs in spatial orientation of the lobster, homarus americanus: differences and overlap
Dana V. Devine,Jelle Atema +1 more
TL;DR: It appears that intact lobsters orient in odor space by tropotaxis principally using aesthetasc receptor input, and lobster with unilaterally ablated lateral antennules and blocked walking leg receptors turned preferentially toward the side of the intact antennule.

TL;DR: In this article, the Straight Line Case is used to fit a straight line by least squares, and the Durbin-Watson Test is used for checking the straight line fit.

The chemical basis of food detection in the lobster Homarus gammarus
TL;DR: A synthetic mixture of chemicals, based on the composition of an extract of squid muscle, has been developed, which is highly attractive for the lobster Homarus gammarus (L.), but none of the components was as attractive as the complete mixture.

Detection of Dissolved Substances by the American Lobster (Homarus americanus) and Olfactory Attraction between Lobsters
TL;DR: Male lobsters responded more frequently to water from a tank with a recently moulted mature female lobster than to water with a nonmoults mature female, and it is possible that moults females release a sex attractant (pheromone).

Comparative chemosensitivity to amino acids and their role in the feeding activity of bathypelagic and littoral crustaceans.
TL;DR: Feeding response exhibition in five marine crustaceans was observed in the presence of a range of concentrations of an amino acid mixture composed of equal parts DL alpha arnino-n-butyric acid, L-glutamic acid and taurine and Panulirus interruptus antennule receptors displayed a degree of specificity to mono- and dicarboxylic amino acids.

The Antennular Activities of the Hermit Crab, Pagurus Alaskensis (Benedict)
TL;DR: The antennular activities of the hermit crab were studied with the aid of motion pictures taken at speeds of 50, 200 and 400 frames/sec and it is proposed that this splaying might facilitate the chemoreceptive process by circulating water around the aesthetasc hairs.
