Tubuca signata (
Hess, 1865)
|
Tubuca signata, the signalling fiddler crab, [1] is a species of fiddler crab that is found in Australia from Queensland to northwestern Australia. [2]
Tubuca signata males have one claw that is significantly larger than the other, while females have two equal-sized smaller claws. The male adult upper claw (pollex) is smooth and bright white while the lower claw (dactyl) has a single groove along its length. The wrist (manus) is red. [3] The male carapace is typically up to 17 mm wide (95% of individuals are this size or smaller), with females slightly smaller. [1]
