Larvae of the tropical spider crab hbinia ferreirae were reared in the laboratory from hatching to metamorphosis, and their growth (dry weight, DW; ash-free dry weight, AFDW) and respiration rates were measured. Variations in the rates and patterns of growth were compared in 2 hatches (larvae from different females).The larvae of the more viable hatch grew continuously during the 2 zoeal stages and the beginning of the megalopa stage, with particularly high instantaneous growth rates in the beginning of each moult cycle. The megalopa showed decreasing biomass values prior to metamorphosis. Ash content increased significantly during and shortly after each ecdysis, then remained constant (zoeae) or decreased slightly (megalopa). In contrast, organic substance (AFDW), increased throughout most of the moult cycle. Respiration (oxygen consumption per individual) increased during development of the zoeal stages, and in the megalopa it followed a sinusoidal pattern. Weight-specific respiration rates were high near ecdysis and low during the intermoult stages of the moult cycle. Energy partitioning was compared among the different larval instars by calculating amounts of energy accumulation from AFDW and metabolic energy loss from respiration. Accordmg to these estimates, net growth efficiency (K2) decreases from the first to the last larval instar (57, 36, and 7 %, respectively), whereas respiratory losses increase in the same order. L. ferreirae has been reported being associated with scyphozoans, and it is speculated that highly increasing mortality as observed during and after metamorphosis might be caused by lack of this specific substrate.

“…Many factors can contribute to reductions in realized dispersal from the potential dispersal predicted from larval life history. Duration of the planktonic phase of marine invertebrates may be much shorter in the field than in the lab (Olson and MacPherson 1987;Prince et al 1987;Cronin et al 1995), which, combined with the short larval period of L. dubia in the laboratory (9 d; Sandifer and Van Engel 1971), suggests that realized dispersal of this species could be relatively restricted. In addition, both physical (Bertness and Gaines 1993;Luettich et al 1999) and behavioral (Cronin and Forward 1986) mechanisms exist that would favor retention of crab larvae in natal estuaries, although it is not known whether these mechanisms operate for L. dubia.…”

“…We suggest that limited larval dispersal because of a brief larval period and reduced transport between areas north and south of Cape Hatteras allows population differentiation in response to differential predation regimes. Furthermore, specialization may be more likely in southern populations because the warmer temperatures characteristic of these habitats speed larval development (Sandifer and Van Engel 1971), increasing the probability that larvae will become competent to settle when still close to their natal habitat. Although further evidence is required, an analogous situation does exist among acorn barnacles, which show localized adaptations to thermal stresses only in bays where flushing rates are low, promoting retention of larvae in natal estuaries and allowing repeated selection for thermal tolerance in adults over generations (Bertness and Gaines 1993).…”

Geographic Variation in Camouflage Specialization by a Decorator Crab

In North Carolina, the decorator crab Libinia dubia camouflages almost exclusively with the chemically noxious alga Dictyota menstrualis. By placing this alga on its carapace, the crab behaviorally sequesters the defensive chemicals of the plant and gains protection from omnivorous consumers. However, Dictyota is absent north of North Carolina, whereas Libinia occurs as far north as New England. Crabs from three northern locations where Dictyota is absent (Rhode Island, Connecticut, and New Jersey) camouflaged to match their environment, rather than selectively accumulating any one species. When D. menstrualis was offered to crabs from northern sites, they did not distinguish between it and other seaweeds for camouflage, whereas crabs from Alabama and two locations in North Carolina used D. menstrualis almost exclusively. In addition, in winter and spring, when Dictyota was seasonally absent in North Carolina, Libinia selectively camouflaged with the sun sponge Hymeniacidon heliophila, which was chemically unpalatable to local fishes. Thus, southern crabs were consistent specialists on chemically defended species for camouflage, while northern crabs were more generalized. The geographic shift in crab behavior away from specialization coincides with a reported decrease in both total predation pressure and the frequency of omnivorous consumers. These shifts in the nature and intensity of predation pressure may favor different camouflage strategies (generalist vs. specialist), contributing to the observed geographic differences in camouflage behavior.

“…Morphological analysis consisted of the following determinations: presence of rostral spines, dorsal and lateral, on the carapace; number of setae of the exopod, endopod, and protopod of the antenna; number of processes; shape and size of the somites of the abdomen; and the presence and number of spines on the furcae and inner margin of the telson. Pre-identification of zoeae was conducted using the original descriptions by Reference [15], [16], [17], [18], [19], [20], [21], [22], [11], [23], [24], [25] and Reference [26]. Diagrams were prepared using a Leica DM750 microscope equipped with a digital camera with 1.3 Moticam 1SPMP and Corel Draw X6 version 16.0.0 program 707.…”

Larval zoeae of Brachyura were collected from five coastal systems located in the State of Veracruz, southwestern Gulf of Mexico. Some morphological differences among the zoeae families have been determined. Morphological analysis consisted of the following determinations: presence of rostral spines, dorsal and lateral, on the carapace; number of setae of the exopod, endopod, and protopod of the antenna; number of processes; shape and size of the somites of the abdomen; and the presence and number of spines on the furcae and inner margin of thetelson. A total of 92839 zoeae of Brachyura were obtained, and 14 families were identified: Aethridae, Calappidae, Portunidae, Menippidae, Panopeidae, Gecarcinidae, Grapsidae, Sesarmidae, Varunidae, Inachidae, Epialtidae, Pinnotheridae, Ocypodidae, and Ucididae. Morphological differences between these families include: Epialtidae and Inachidae lack lateral spines; Pinnotheridae lacks spines on one side of the carapace,and there may be a wing shape on the fifth abdominal somite; the exopod of the antenna is short in Grapsidae and well-developed in Ucididae; the fourth abdominal somite is significantly expanded in Ocypodidae; the family Gecarcinidae lacks spines on the furcae; Portunidae, Calappidae, and Aethridae have two or three spines on the furcae, but differ in the size of the exopod of the antenna relative to the size of the rostrum; and Sesarmidae and Varunidae differ in the lateral spines on the carapace. A key for identification of the zoeae to the family level is presented.This is the first key for Brachyura zoeae from the southwestern Gulf of Mexico.
