Biochemical composition of body compartments during the reproductive cycle of the starfish Allostichaster capensis in Patagonia, Argentina
Allostichaster capensis (Perrier, 1875) (= inaequalis) is a fissiparous starfish inhabiting the South Atlantic Ocean coasts. On the Patagonian coast, it displays an annual sexual and asexual reproductive cycle. Fission is most frequent during the austral summer (November-January) and arm regeneratio...
