Tumidodromia dormia

Tumidodromia dormia (Linnaeus, 1763) Fig. 18 Material examined MAURITIUS • 1 ♀ (135.7×109.9); 1850; dry specimen from the “Sala del Mar” exhibition; MNCN20.04/00032. Remarks Tumidodromia dormia is the largest known sponge crab (up to 200 mm cw), and inhabits shallow waters (McLay 2009). Only two ovigerous female specimens of this species have been captured (McLay 2009), and our specimen is a female, but due to its fragility, it is not convenient to manipulate the specimen, therefore it is not known if it is ovigerous or not. For identification see also Lewinsohn (1984) and McLay (2001, 2009).
