“…Amphipods, lobsters and crabs excrete specific sexually attractant pheromones which affect chemoreceptors (e.g. Dahl, Emanuelsson & von Mecklenburg, 1970). These results show that the chemical senses of some crustaceans have a high sensitivity and also a good capacity for qualitative discrimination.…”

Specific 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 degrees C. Work on planktonic crustaceans suggests that they respond particularly to changes in temperature by klinokinesis and orthokinesis. The thermal behaviour of crustaceans is modified by thermal acclimation among other factors. The acclimation of the critical maximum temperature is an example of resistance acclimation, while the acclimation of preference behaviour may be classified as capacity acclimation of some other function. In crustaceans, the use of the concepts stenothermy and eurythermy at the species level is questionable, and it is not possible to divide crustacean species into thermal guilds as suggested for fishes. Thermal preference behaviour contributes to fitness in different ways in different species, often by maximising the aerobic metabolic scope for activity. In crustaceans the peripheral nervous system seems to have retained the capacity for thermosensitivity and thermal acclimation independently of the central nervous system control of behaviour.

“…The swimming activity is to achieve mating contacts (Fincham 1970a(Fincham , 1972Jones et al 1973). Female pheromones are involved (Dahl et al 1970) and this separation in time could be an effective means of ensuring that males locate a mate of the same species.…”

Twenty-four hour, lunar-month, and seasonal, samples of amphipods were taken using a light trap from Karaka Wharf, Wellington Harbour, New Zealand (41° 16'S, 174° 51'E). Average number of amphipods for the 31 night samples was 255 per 30-min sample; few amphipods were caught in daylight samples. Algae-dwelling species formed 80.6%, infaunal species 16.6%, and pelagic species 2.8% of the total amphipods caught. Infaunal species appear early in the dark period and numbers decline during the night; numbers of algae-dwelling species build up during the night and reach a peak before dawn. Numbers of infaunal species increase on days 1 and 20 of the lunar month, whereas algae-dwelling species show no lunar rhythmicity but numbers increase in turbulent sea conditions. Seasonal sample numbers were erratic, greatest numbers being taken in early August and small peaks coinciding with spring and autumn sea temperature changes.Peak, swimming activity by adults of the infaunal lysianassid Parawaldeckia stephenseni was on the early ebb tide; juveniles continued to swim until dawn. Ovigerous females were present in the swimming population from days 1 to 12 of the lunar month; non-ovigerous females are mated by day 24 and disappear from the swimming population. Males swim throughout the lunar month. Average number of eggs carried is 12, females mature at 3.6 mm, and numbers of eggs carried increase after each successive moult.

“…Both observational and experimental evidence indicate that behavioral changes in males prior to mating, such as searching or reduced aggressive behavior, are induced by water soluble substances released by the female. Such pheromones have been indicated in a variety of Crustacea, e.g., crabs (Portunus sanguinolentus, Ryan, 1966;Carcinus maenas, Eales, 1974; Pachygrapsus crassipes, Cancer antennarius, C. anthonyi, Kitteredge et al, 1971), lobsters (Homarus americanus, McLeese, 1970; 158 R.T.BAUER Atema and Engstrom, 1971), crayfish (Procambarus clarkii, Ameyaw-Akumfi and Hazlett, 1975), amphipods (Gammarus duebeni, Dahl et al, 1970) and copepods (Labidocerajollae, Kitteredge et al, 1974).…”

Newly molted female Heptacarpus paludicola with full ovaries evoke a copulatory response from males upon contact. Males recognize a matable female for copulation by apparent contact chemoreception with the antennal flagellae. Observational evidence in this species and in several others cited in the literature did not strongly suggest distance perception of matable females by males. However, when tested in an experimental "olfactometer" evidence was obtained to indicate that matable females of this species emit a pheromone that increases activity of males, whereas hard-shelled, embryo-bearing females do not.Although newly molted females with full ovaries were by far the most effective in evoking copulatory behavior from males, newly molted females without ovarian development (due to parasitization or food deprivation) showed varying degrees of attractiveness. Newly molted males were not attractive to other males. The duration of attractiveness to males was less than one day after matable females had molted. Chemicals associated with the hardening of the cuticle are suggested as a possibility for the apparent contact pheromone involved in sex recognition.
