Report of opportunistic feeding habits by Vences’ river crab Hydrothelphusa vencesi (Brachyura: Potamoidea: Potamonautidae)

Hydrothelphusa vencesi is an endemic Madagascan freshwater crab whose ecology and behaviour are largely unknown. We report here on an episode of the feeding habits of two individuals of H. vencesi on a giant fire millipede (Aphistogoniulus infernalis) and on a cicada (Malagasia inflata) in south-eas...

Description
Summary:Hydrothelphusa vencesi is an endemic Madagascan freshwater crab whose ecology and behaviour are largely unknown. We report here on an episode of the feeding habits of two individuals of H. vencesi on a giant fire millipede (Aphistogoniulus infernalis) and on a cicada (Malagasia inflata) in south-east Madagascar. This represents a first report on the diet of this species and an example of its opportunistic feeding behaviour, shedding some light on the possible trophic link between an aquatic and a terrestrial system.
