I found this elusive crab species known as Krabby really far in land. In fact these species are usually found closer to the sea shore. My companions and I decided to capture it to learn more about its nature and its evolution over time.

Description

While cast netting for whatever fish might be in the surf at Cherry and Webb Beach in Westport, MA, I captured 3 speckled crabs that had similar but opposite patterning to the (common) lady crab (Ovalipes ocellatus), in that the carapace spots were pale, ringed with sandy gray-brown. When I first encountered this species in August 2015 (50+ captured), I initially assumed they were juv. blue crabs, based on the sharp extensions to their carapace. However I noticed that the points were more saw-toothed than slender (as in blue crab), and the speckling was not consistent with juv. blue crabs I have captured. I am now certain of this species' identity.
