The fiddler crab Uca annulipes (Milne Edwards, 1837) is thought to be widely distributed in the Indo-West Pacific. Previous studies showed consistent morphological differences between East African populations and those from the eastern Indian Ocean and

The community structure of the tropical fiddler crab Uca annulipes (H. Milne Edwards) has been studied in Mozambique for the first time. Ten 0.25 m2 squares were randomly sampled on a monthly basis during low tide periods from January to December 2002

Fiddler crabs are known as the most conspicuous bioturbating animals in mangrove forest, which by their burrowing activities promote nutrient cycling in ecosystems. Mangroves, crabs and bacteria are connected in the form of positive feedback loop, whereby

Mangrove ecosystems are sites with high biodiversity of benthic fauna, and fiddler crabs (genus Uca) are common benthic fauna in mangroves. The North Sulawesi in Indonesia has a good condition of mangrove while the information of the fiddler crabs is
