Mangrove crab

Crabs that live on or among mangroves

Mangrove crabs are crabs that live in and around mangroves. They belong to many different species and families and have been shown to be ecologically significant by burying and consuming leaf litter. By shredding and burrowing the leaf litter, mangrove crabs are able to prevent tidal export, which in turn helps retain the nutrients present in their habitats.This makes the nutrients around mangrove trees more available to other organisms, and thus they have an important role in maintaining ecological relationships and processes within their environments.
