“…The spider crab, Libinia ferreirae Brito Capello 1871, is exclusively distributed in the western Atlantic Ocean (Costa Rica to Uruguay) from coastal areas up to depths of 35 m, mainly in muddy bottoms (Melo, 1996;Tavares & Santana, 2012). This Majoidea crab engages in symbiotic relationships throughout its lifespan.…”

Ecology of the spider crab Libinia ferreirae (Brachyura: Majoidea): ontogenetic shifts in habitat use

We described the ecology of the spider crab Libinia ferreirae testing the habitat segregation during the ontogenetic shifts. Collections were performed monthly by trawling along the coastal area of Cananéia, São Paulo State (southeastern Brazil). Medusae were examined for the presence of any symbionts, and crabs were classified as juveniles (abdomen sealed to the sternite), adults (unsealed abdomen), and ovigerous females (embryos adhered to the pleopods). The environmental factors related to the water column were obtained using a multiparameter probe. In total, 564 adults and 357 juveniles were collected. However, all juveniles were obtained in association with Lychnorhiza lucerna medusae. An increase in the abundance of ovigerous females was observed as chlorophyll levels (phytoplanktonic production) increased, which is consistent with the patterns proposed for crustaceans with planktotrophic larval stages, i.e., the association of larval hatching with oceanic productivity could explain the success in juvenile recruitment approximately two months after the peak in the abundance of ovigerous females (crosscorrelation: r = 0.96). This spider crab shows an ecological strategy of habitat segregation among juvenile and adult individuals, thus avoiding competition for resources among different life cycle stages.

“…We employed a rapid and simple DNA extraction method using prepGEM ® Insect kit, which can process hundreds of samples in a day and is scalable to the size of the sample being tested, which is especially important for immature stages of insects which are difficult to differentiate morphologically . For example, while the protocol suggests using a 40 µL extraction volume, this study found that for samples of larvae and pupae the volume can be reduced proportionally from 40 to 20 µL, and the volume of eggs can be reduced from 40 to 10 µL owing to the small size of the sample.…”

“…The distribution of the spider crab, L. ferreirae is restricted to the western Atlantic, from Costa Rica to Uruguay, and inhabits depths up to 35 m (Melo, 1996;Tavares and Santana, 2012). This species also maintains a symbiotic relationship with the jellyfish, Lychnorhiza lucerna, (Haeckel, 1880) (Scyphomedusa).…”

“…To date, studies on this spider crab L. ferreirae have addressed their larval development (Anger et al, 1989;Bakker et al, 1990), symbiotic relationships (Nogueira Jr. and Haddad, 2005;Winter and Masunari, 2006;Gonçalves et al, 2016;2017b), morphology and maturity (Tavares and Santana, 2012;Gonçalves et al, 2017a) and distribution (Braga et al, 2007). However, little is known about the growth of this species.…”

“…Crabs were identified according to the morphological features noted in the studies carried out by Melo (1996) and Tavares and Santana (2012). Specimens were sexed based on the shape of the abdomen (an elongated shape for males and an oval shape for females) and the number of pleopods (two pairs of pleopods for males and four pairs for females) (Ingle, 1977;Sampedro et al, 1999).…”

Growth and longevity of the spider crab Libinia ferreirae (Majoidea, Epialtidae)

We estimated the growth parameters of the spider crab, Libinia ferreirae (age, asymptotic size and growth rate) using the von Bertalanffy growth equation model. We obtained nine cohorts for female carapace asymptotic width (CW ∞ ) = 64.32 mm, growth coefficient (day -1 ) (k) = 0.0027 e t 0 = 0.77 days) and seven for males (CW ∞ = 81.93 mm, k= 0.0021 e t 0 = 0.49 days). The longevity for males was higher than that for females, estimated 2,156 days (5.91 years) and 1,706 days (4.68 years), respectively. The growth curves for males and females differed (F = 34.67 e p < 0.001). Males reached gonadal maturity before morphometric maturity and occurred at 8.8 and 16.6 months of life, respectively. Females reach gonad and morphometric maturity synchronously and this was estimated to occur at about 11.42 months of life. These crabs invest a great amount of energy in growth during a brief period of their development until reaching the terminal moult. This growth strategy would bring less wear to the organism and consequently a greater longevity.
