“…If these heterosexual pairs persist for long time periods, their members may reproduce repeatedly with the same partner. This has been inferred for many snapping shrimp species, which are commonly found in heterosexual pairs (Nolan & Salmon, 1970;Schein, 1975;Yanagisawa, 1984).…”

This study examined the association pattern of two snapping shrimp species that inhabit burrows at exposed rocky shores of the Chilean Paci¢c coast. The two species Alpheus inca and Alpheopsis chilensis were frequently found to share the same burrows. In most burrows an heterosexual pair of each species was found. A strong positive correlation between the body length of female and male conspeci¢cs cohabiting in a burrow was found both for Alpheus inca and for Alpheopsis chilensis. Similarly, a positive correlation existed between the mean body length of Alpheus inca and that of Alpheopsis chilensis occurring together in one burrow. Thus, a size-relationship between burrow cohabitants exists both in the intra-speci¢c as well as in the inter-speci¢c association of these shrimps. Most females, regardless of their reproductive stage, were accompanied by males. Within a particular burrow, females of the two species often were in the same reproductive stage, i.e. both were with embryos in a similar developmental stage, or both were without embryos. These data suggest that male and female conspeci¢cs, as well as the pairs of the two species, remain together in the same burrow for relatively long time periods. It is proposed that the intra-speci¢c communication system of snapping shrimp facilitates the development of inter-speci¢c associations, such as the one reported herein.

“…Nolan and Salmon, 1970;Duffy et al, 2002) and interspecific (defense). In Alpheus, sexual pairs are size matched, with females generally having a slightly larger body (Schein, 1975;Hughes, 1996;Rahman et al, 2002) and relatively smaller major chela than males do (e.g. Dawes, 1934;Nolan and Salmon, 1970;Schein, 1975Schein, , 1977Knowlton ,1980;Boltana and Thiel, 2001;Mathews, 2002).…”

Synalpheus paraneptunus (Crustacea: Decapoda: Caridea) populations with intersex gonopores: a sexual enigma among sponge-dwelling snapping shrimps

Caridean shrimp populations are usually gonochoristic, i.e., composed of separate sexes; however, some carideans are protandric sex changers or simultaneous hermaphrodites. In this contribution we investigated the sexual composition and its determination in two sponge-dwelling Synalpheus species with different degrees of sociality. Because the usual external sexing methods (presence or absence of appendices masculinae in males) can not be used in Synalpheus spp., we sexed individuals by observation of male and female gonopores using scanning electron microscopy (SEM). We found that populations of two species of the Synalpheus paraneptunus complex consist almost entirely of individuals with both male and female gonopores (termed herein "intersexes"). Such a high incidence of intersexes has not been previously reported in other decapods. We performed morphological and behavioral observations to test various hypotheses explaining the presence of intersex gonopores. Whereas protandry and simultaneous hermaphroditism are not likely to occur in these two species, capacity of immature helpers to mature as either sex, or developmental anomaly without adaptive significance could explain the presence of both female and male gonopores in these shrimps.

“…Snapping shrimp usually occupy a shelter together in heterosexual pairs (Schein, 1975(Schein, , 1977Nolan and Salmon, 1970). Females can reproduce every three to four weeks, which is concurrent with their moult cycle.…”
