Gecarcinus lateralis
Gecarcinus lateralisAlso known as Blackback Land Crab, Bermuda Land Crab, Red Land Crab, Moon Crab
Blackback land crabs dig deep burrows along coastal woodlands and sandy dunes throughout the Caribbean region. They emerge primarily at night or after rain to forage on fallen fruit, leaves, and organic detritus. During female spawning migrations, huge numbers trek down to the shore to release their eggs directly into the surf.
