This is a species of crab commonly found around the intertidal areas and throughout the Gulf of California. Like all other fiddler crabs, it can be recognized by its oversized front claw. For the most part, they remained buried under the sand, rising during the mid-morning and during the night.
Although shrimp are primarily trawled in the gulf, these creatures are also harvested along with them. Thousands of these are caught each year by fisheries around the gulf.
Although the harvest of crabs and shrimp is regulated, the hunt for these creatures can
still cause harm to other species, like the dangerously endangered vaquita.
