Associações entre medusas (Cnidaria) e isópodos (Crustacea) nos litorais do Paraná e Santa Catarina, Brasil

Resumo

O presente trabalho refere-se à associações entre isópodos e
macromedusas nos litorais do Paraná e de Santa Catarina, sendo
este o primeiro registro. Quatro espécies de Isopoda foram
encontradas: 1. Nerocila fluviatilis Schioedte & Meinert, 1881 e
2. Cymothoa catarinensis Thatcher et al. 2003 (Cymothoidae)
parasitando, respectivamente Chiropsalmus quadrumanus (Müller,
1859) (Cubozoa) e Chrysaora lactea Eschscholtz, 1829
(Scyphozoa: Semaeostomeae); 3. Ancinus brasiliensis Castro, 1959
(Sphaeromatidae) inquilino de C. quadrumanus e 4. Synidotea
marplatensis Giambiagi, 1922 (Idotheidae) associada a três
espécies: C. lactea, Lychnorhiza lucerna Haeckel, 1888
(Scyphozoa: Rhizostomeae) e Olindias sambaquiensis Müller, 1861
(Hydrozoa: Limnomedusae).

Associations between medusae (Cnidaria) and isopods (Crustacea) at the littoral of Paraná and Santa Catarina State, Brazil

Abstract

The present study comments on isopods found associated on
macromedusae at the littorals of the Paraná and Santa Catarina
States, Southern Brazil. This is the first communication of these
interactions. Four species were found: 1. Nerocila fluviatilis
.Schioedte & Meinert, 1881 and 2. Cymothoa catarinensis Thatcher
et al. 2003 (Cymothoidae) parasite respectively Chiropsalmus
quadrumanus (Müller, 1859) (Cubozoa) and Chrysaora lactea
Eschscholtz, 1829 (Scyphozoa: Semaeostomeae); 3. Ancinus
brasiliensis Castro, 1959 (Sphaeromatidae) living on C.
quadrumanus and Synidotea marplatensis Giambiagi, 1922
(Idotheidae) on C. lactea, Lychnorhiza lucerna Haeckel, 1888 (Scyphozoa: Rhizostomeae) and Olindias sambaquiensis Müller,
1861 (Hydrozoa: Limnomedusae).
