Tubuca alcocki is a species of fiddler crab. Its range includes most of the northern Indian Ocean, from western Thailand (facing the Andaman Sea), through the Bay of Bengal and India, to the Red Sea.^[1]^[2]

Etymology[edit]

The specific name alcocki is in honor of Alfred William Alcock, the naturalist who recorded the species from India and Pakistan as Uca urvillei.^[1]

Description[edit]

Carapace and legs brown or dark brown. Major cheliped with fingers white in adults and orange in young. Females with orange cheliped with blue tinge. Carapace of male is trapezoidal, smooth with distinct, narrow median groove. Anterolateral margin is acutely triangular. Major cheliped with dactylus usually longer than palm. Carapace of female is also trapezoidal. Anterolateral margin broadly triangular.^[1]

Ecology[edit]
