Land Crab

This nocturnal crab digs burrows — sometimes as long as 1.5 metres (4.9 ft) — in the coastal rainforests of Central America, and is common along the coasts of Costa Rica, Panama, and Nicaragua. There it lives in the forest at least some of its adult life, but needs to return to the ocean to breed. The halloween crab is very territorial and will defend itself if threatened. It is largely herbivorous, and consumes leaf litter and seedlings. They will, however, also take animal matter if available.(wikipedia)
