Abstract:
Environmental changes in the intertidal area causes mangrove degradation and aberration
resulting in an impact on the existence of fiddler crab. This study aimed to investigate fiddler
crabs (ocypodidae) from the intertidal environment of Bengkalis Regency, Riau. Fiddler crabs
were taken in October 2020 in two different locations (Bukit Batu and Tanjung Leban).
Speciments were collected using a hoe or by hand capture. The results of research in the
intertidal area of Bengkalis Regency found six species from two genera. The two species belong
to the genus Austruca (A. annulipes A. perplexa), and four species belong to the genus Tubuca
(T. typhoni, T. urvillei, T. dussumieri, T. rosea).
