Shrimps remove ectoparasites from fishes in temperate waters

Stenopodidean shrimps (Crustacea: Decapoda) from New Caledonian waters.

A small collection of 159 specimens of stenopodidean shrimps from New Caledonian waters has been studied and found to represent 13 species in 6 genera, adding 8 new species of stenopodideans to the Southwest Pacific fauna. Two new species are recognized, Richardina crosnieri n. sp. and Spongiocaris neocaledonensis n. sp. Two species of Odontozona are redescribed. Illustrations are provided for ...

Records of regalecid fishes in Argentine waters

The first two specimens of Regalecus glesne Ascanius, 1788, collected in the Argentine Sea, at Playa Unión beach, 43o 18' S, 65o 02' W are reported. Body measurements, meristic characters and morphological data are given. The most important differences with two other regalecid species, R. russelii Cuvier and R. kinoi Castro-Aguirre et al. 1991, from the Pacific coasts of Mexico, are considered....

Aggregation and species coexistence of ectoparasites of marine fishes.

Interspecific interaction may lead to species exclusion but there are several ways in which species can coexist. One way is by reducing the overall intensity of competition via aggregated utilisation of fragmented resources. Known as the 'aggregation model of coexistence', this system assumes saturation and an equilibrium number of species per community. In this study we tested the effects of i...
