| Cardisoma crassum | |
Cardisoma crassum, known as the mouthless crab, is a species of terrestrial crab found in the coastal tropical eastern Pacific from Baja California to Peru. It has a purplish-blue shell, red legs and white main pincer. Cardisoma crassum is common among mangrove roots, where it builds its burrow. Burrows dug by Cardisoma crassum are complex, often over 2 meters deep and located in high areas of mangroves with a water reservoir at the bottom of the burrow.[2] A new species of sand fly in the genus Culicoides was found to be living and breeding in mouthless crabs' burrows, and was subbed C. cancer due to the crab connection.[3]
Classification
[edit]Cardisoma crassum is in the family Gecarcinidae, also known as the land crabs. Sidney Irving Smith described the species in 1870.[4]
Distribution
[edit]Mouthless crabs live in the eastern Pacific region, just one of three species of land crabs found there. They are distributed from Baja California and the neighbouring Gulf of California southwards to Peru and sometimes into Chile.[5][6]
