These crabs are typically found in sandy beaches and mudflats, where they burrow into the substrate to escape predators and regulate their body temperature. Leptuca coloradensis is a highly adaptable species, with its distribution extending across a range of marine zones, from the supralittoral zone to the lower intertidal zone, demonstrating its ability to thrive in varied environments.
Taxonomy
Leptuca coloradensis is a member of the Class Malacostraca, Order Decapoda, and Family Ocypodidae. The family Ocypodidae, also known as the ghost crabs, comprises a diverse group of crabs that exhibit a variety of adaptations for life in the intertidal zone. These crabs are characterized by their slender legs, prominent eyes, and their ability to burrow in the sand.
Feeding
Leptuca coloradensis is an omnivore, feeding on a variety of food sources including algae, detritus, and small invertebrates.
