Tubuca flammula, commonly known as the flame-backed fiddler crab is a species of fiddler crab that is found in the northwest of Western Australia, the northern part of the Northern Territory and the western half of Papua New Guinea[1] [2]
Tubuca flammula was formerly a member of the genus Uca, but in 2016 it was placed in the genus Tubuca, a former subgenus of Uca.
Like other fiddler crabs, Tubuca flammula males have one claw that is significantly larger than the other, while females have two equal-sized smaller claws. It has a black carapace with two white or pinkish parallel marks running fore and aft near the centre and a solid red band across the front of the carapace. The claws are bright red-orange and the eyes are close together.[3]
