Crab; Cape river - Potamonautes Perlatus

Unread postby arks » Wed Nov 20, 2013 3:05 am

I saw this very shy crab in my garden in Darling at the end of August 2013. Can anyone tell me what sort of crab it is?

The crab indeed seems shy.

My guess is that it is : Cape river crab (Potamonautes perlatus), which frequents most of the Cape freshwater spots, and is also found in most other rivers throughout our country.

Thanks so much! I googled a bit and that would indeed seem to be my little crab. :thumbs_up:

It was VERY shy, backing quickly into the protection of those leaves, so I had next to no time to get a photo :roll:
