Vulnerability

Atelecyclus is a small but mobile crab that lives on sandy & gravel substrates. The carapace is 3-4cm in length & the crab is able to burrow into sediments. It is vulnerable to dredging but is well-adapted to resurface from sediments deposited during the dredging.

 

Recoverability

There is little information on the life-span & reproductive biology of Atelecyclus. The sexes are separate & fertiliisation is internal. The planktotrophic zoea larvae are released into the water column after a short period of incubation by the female but there is insufficient information to assess the fecundity & dispersal potential for this genus. It is likely to grow to adult size in <3yrs & to have a moderate dispersal potential in the plankton.
