Crustacea--Florida

The xanthid crabs Eurypanopeus depressus and E. dissimilis co-occur among oysters on seawalls in southeastern Florida. Population dynamics and aspects of the life history of these two species were compared during a 1-year period, at two study sites. There were no interspecific differences in adult size for either sex. For both species, females were significantly more abundant than males. E. depressus was more abundant at one study site, E. dissimilis at the other. Ovigerous females were found year-round. Number of eggs per female of both species increased with increasing carapace width. Recruitment of young into the population occurred year-round.

The caprellid fauna from the shallow waters of Florida's southeastern
coast were investigated. Eleven species of caprellid amphipods
were found: Caprella andreae, Caprella danilevskii, Caprella equilibra,
Caprella oenantis, Caprella scaura, Fallotritella biscaynensis,
Hemiaeqina minuta, Luconacia incerta, Paracaorella pusilla, Paracaprella
tenuis, and Phtisica marina. All species were new distribution records
for the collection locations except for five species at the Miami site
and two species at the Fort Lauderdale site.
