“…This type of hermaphroditism has been demonstrated in at least one other barbouriid shrimp, Parhippolyte misticia (Onaga et al, 2012), and in a number of species of the more distantly related hippolytid genera Lysmata Risso, 1816and Exhippolysmata Stebbing, 1916(Bauer and Holt, 1998Bauer, 2000;Baeza and Bauer, 2004;Baeza, 2006;Braga et al, 2009;Fiedler et al, 2010). The morphological and anatomical details of the presumed hermaphroditism in J. antiguensis remain to be investigated.…”

Confirmation of the presence of Janicea antiguensis (Chace, 1972) (Decapoda: Barbouriidae) in northeastern and eastern Brazil

The barbouriid shrimp Janicea antiguesis (Chace, 1972) is reported from Porto de Galinhas and Tamandaré in Pernambuco and Guarapari in Espírito Santo, Brazil. These records confirm the presence of J. antiguensis in northeastern and eastern Brazil, considerably extending its Brazilian range from Fernando de Noronha to southern Espírito Santo and also representing the first record of this species from mainland coastal reefs. In Brazil, J. antiguensis occurs in or near marine reef caves, typically at depths between 5 and 15 m, and can be most easily observed while scuba diving at night. Colour photographs of J. antiguensis from various Atlantic localities are provided and its colour pattern is compared to that of the closely related Indo-West Pacific barbouriid shrimp, Parhippolyte misticia (Clark, 1989). Some in situ observations are provided for the Porto de Galinhas population of J. antiguensis. Multiple observations of pairs with both individuals brooding embryos at different developmental stages suggest protandric simultaneous hermaphroditism in J. antiguensis.

The sexual system of two caridean shrimps (Processa riveroi and P. bermudensis) was investigated, stimulated by reports of male to female sex change (protandry) in Processa edulis from European waters. Shrimps used in the study were obtained from monthly samples taken from March 1982 to February 1983 in a Thalassia -Syringodium seagrass meadow in Puerto Rico. Observations on size, sex, and reproductive condition were used to construct monthly size -frequency distributions and sex-ratios by size-class (SC). Males were smaller than reproductive females, but there was extensive overlap in size between males and immature females. A sex-ratio (SR) analysis by SC of the overall year-long population sample showed an equal or female-biased SR in the smallest SC, a male-biased SR in 1-3 intermediate SC, with larger SC dominated by females incubating embryos. Such a population structure might result from slower growth in males than females and higher mortality in larger males. Observations on and allometric analysis of sexual characters failed to identify transitional individuals (sex-changers) intermediate in reproductive morphology between males and females. Thus, a hypothesis of protandry is rejected, and that of gonochory (separate sexes) is accepted in these two Processa species, revealing possible variation in sexual systems among Processa species.

“…Among decapod shrimps, all Exhippolysmata and Lysmata species examined, and one species of Parhippolyte, have been shown to be protandric simultaneous hermaphrodites, in which shrimps are initially males and later turn into functional simultaneous hermaphrodites (Baeza et al 2009;Braga et al 2009;Onaga et al 2012). Protandrous sequential hermaphroditism has been found in a number of caridean species (Bauer 2000;Chiba 2007), e.g.…”

Social Recognition in Invertebrates

View full text Add to dashboard Cite

Common in most aquatic environments, shrimps occur in a wide range of social associations with conspecific and other species, and express various levels of social recognition. We review the mechanisms and forms of social recognition in shrimps, emphasizing the Caridea. Most research has been conducted on Alpheidae, Hymenoceridae, Hippolytidae, Palaemonidae and Stenopodidae. The olfactory first and chemotactile second antennae are important in perceiving waterborne cues/ pheromones and contact pheromones. Potential distance and contact pheromones have been strongly suggested by behavioural studies in several species and even tentatively identified in a few species. All forms of social recognition and interspecific communication have been documented in shrimps, including recognition by mate, size, rank, kin and individual. Given the diversity of ecology, mating and social behaviour, and the previous research on social recognition in caridean shrimps, this group is a promising productive model taxon for studies in animal communication.
