The oldest freshwater crabs: claws on dinosaur bones [PDF]

open access: yesScientific Reports, 2019
Abstract With approximately 1,500 extant species, freshwater crabs (Decapoda: Brachyura) are among the most diverse decapod crustaceans. Nevertheless, their fossil record is extremely limited: only Potamidae, Potamonautidae and Trichodactylidae are reported up to the Eocene of the Neotropics so far.

Sexual Disruption in the Freshwater Crab (Geothelphusa dehaani) [PDF]

open access: yesIntegrative and Comparative Biology, 2005
To clarify the effect of environmental endocrine disruptors on the induction of secondary sexual characteristics in wild animals, we observed 1,527 male and 1,847 female specimens of sexually mature Japanese freshwater crabs, Geothelphusa dehaani, collected at 12 sample points from 10 rivers in Sasebo City, Nagasaki Prefecture, Japan.
