“…A. aurita (Linnaeus, 1758) A. aurita is distributed worldwide in coastal waters and is associated with a wide range of water temperatures (0-36°C) and salinities (3-36‰) (Arai, 1997;Martin, 1999). The cases of A. aurita blooms have been reported in many coastal areas, including the Baltic region, Japan, Korea, India and Australia (Mills, 2001).…”

Associations between jellyfish and other organisms are frequently reported. Neverhteless, few of those records include crabs inhabiting medusae. Lychnorhiza lucerna Haeckel, 1888 were sampled (n = 1988) on the coast of the State of Paraná (25º20'-25º55'S, 48º10'-48º35'W), southern Brazil, from December 1997 to December 2004. Eight percent (166 individuals) of the medusae had one spider crab Libinia ferreirae Brito Capello, 1871 living within its subgenital porticus or on the oral arms. Megalopal stages of the same crab were also found on three jellyfish. All crabs associated with L. lucerna were young and smaller (< 3 cm) than solitary crabs caught on the bottom. Thus, L. ferreirae probably colonizes the jellyfish as a late larva and uses it as a floating nursery before becoming free-living on the ocean bottom as a typical adult crab.

“…If species-level identification was not possible, specimens were identified to genus. Species identifications and taxonomy were based on Uchida (1947), Massin & Tomascik (1996), Arai (1997), Wrobel & Mills (1998), Bouillon (1999), Mianzan &Cornelius (1999), andPugh (1999). Suborders within Rhizostomeae and subfamilies within Ulmaridae (Mianzan & Cornelius, 1999) are ignored because equivalent taxonomic ranks are not commonly recognized within other orders of Scyphozoa.…”

“…Behavioural variation, like morphological variation, is widely known (Arai, 1997) but most is poorly documented in medusae. Relatively wellknown variations in diel vertical migration and prey selection often have been attributed to ontogenetic and environmental factors or ascribed to intra-specific variability and interpreted as evidence of phenotypic plasticity.…”

Some implications of molecular phylogenetics for understanding biodiversity in jellyfishes, with emphasis on Scyphozoa

Statistical phylogenetic analyses of 111 5.8S and partial-28S ribosomal DNA sequences (total aligned length=434 nucleotides) including jellyfishes representing approximately 14% of known scyphozoan morphospecies (21% genera, 62% families, and 100% orders) are presented. These analyses indicate stauromedusae constitute a fifth cnidarian class (Staurozoa) basal to a monophyletic Medusozoa (=Cubozoa, Hydrozoa, and Scyphozoa). Phylogenetic relationships among the medusozoans are generally poorly resolved, but support is found for reciprocal monophyly of the Cubozoa, Hydrozoa, Coronatae, and Discomedusae (=Semaeostomeae + Rhizostomeae). In addition, a survey of pairwise sequence differences in Internal Transcribed Spacer One within morphospecies indicates that scyphozoan species diversity may be approximately twice recent estimates based on morphological analyses. These results highlight difficulties with traditional morphological treatments including terminology that obfuscates homologies. By integrating molecular phylogenetic analyses with old and new morphological, behavioural, developmental, physiological, and other data, a much richer understanding of the biodiversity and evolution of jellyfishes is achievable.
