Spatial and Seasonal Distributions of Callinectes Danae (Decapoda, Portunidae) in Ubatuba Bay, São Paulo, Brazil [PDF]

Journal of Crustacean Biology, 2001
The spatial and seasonal distributions of Callinectes danae Smith, 1869, in Ubatuba Bay, Sao Paulo, Brazil, were investigated as a part of a broad study on the general biology of portunids along the northern coast of Sao Paulo State, Brazil. Swimming crabs were collected during one year, from September 1995 to August 1996, along eight transects ...

Comparação do peso dos quelípodos e crescimento em duas espécies de "sirís" do gênero Callinectes (Brachyura, Portunidae)

Brazilian Archives of Biology and Technology, 1998
Neste trabalho, as espécies C. danae e C. ornatus foram comparadas quanto ao peso dos quelípodos. Os siris foram coletados com 2 redes de arrasto do tipo "otter trawl" na Enseada de Ubatuba (23° 26' S e 45° 02' W). As constantes alométricas obtidas foram

Epibiosis in decapod crustaceans by stalked barnacle Octolasmis lowei (Cirripedia: Poecilasmatidae)

Zoologia (Curitiba), 2013
Stalked barnacles Octolasmis lowei Darwin, 1851 are frequently found attached to decapod crustaceans. Their epibiotic association depends on many factors, which are mainly related to characteristics of the host's biology.

Do the day/night periods and tidal cycles modulate the abundance and distribution of Callinectes danae Smith, 1869 (Brachyura, Portunidae) in an estuary-bay complex from southeastern Brazil?

Nauplius, 2020
We investigated the abundance and spatial distribution of Callinectes danae Smith, 1869 during the day/night periods and tidal cycles in a coastal area of Brazil. Sex ratio, size class distribution, and mean sizes of males and females were also analyzed.

Contractions induced by sodium withdrawal in crab (Callinectes danae) muscle fibres.

The Journal of Physiology, 1983
A study was made of the effects of Na removal on the resting tension of single muscle fibres of the crab Callinectes danae. Reduction of [Na]o (replacement with Li, Tris or choline) below a threshold value, typical for each fibre, induced spontaneous, local contractions randomly dispersed along the fibres; this was followed by propagated contractile ...
