'''''Cyclocoeloma''''' is a [genus](/source/genus) of [crab](/source/crab)s in the [family](/source/Family_(taxonomy)) [Majidae](/source/Majidae), containing the single species '''''Cyclocoeloma tuberculata'''''.

==Description==
''Cyclocoeloma tuberculata'' is a small size [spider crab](/source/spider_crab), its [carapace](/source/carapace) reach an average length of 45mm from the rostral area to posterior tip.<ref>J.C. den Hartog, "Associated occurrence of Cyclocoeloma tuberculata and species of Discosomatidae, ZOOLOCISCH E MEDEDELINGE,1990</ref> The back side of the [carapace](/source/carapace) is rounded but the rostral area is going relatively far ahead and looks like a head with lateral position of the eyes.
However, it's quite difficult to observe the [carapace](/source/carapace)'s shape on a living animal because it's covered with [corallmophs](/source/Corallimorpharia).
The four ambulacra, when not too much decorated, are creamy colors with brown bands. In the [majids](/source/Majidae), the decoration is fixed on the [carapace](/source/carapace) and legs via hooked hairs.<ref>D Jones & G Morgan, "A field guide to crustaceas of Australian waters", Western Australian Museum, 2002</ref> The [claws](/source/claws) are quite small and are also used to decorate themselves.
The reason they cover their body is to camouflage themselves from potential predators, especially during the day; ''C.&nbsp;tuberculata'' fixes [corallimorphs](/source/Corallimorpharia) of the family [Discosomatidae](/source/Discosomatidae) to its [carapace](/source/carapace), and [soft coral](/source/Octocorallia)s of the family [Xeniidae](/source/Xeniidae) to its legs.<ref name="Hartog"/>

==Distribution==
''Cyclocoeloma tuberculata'' is widespread throughout the [tropical](/source/tropical) waters of the central [Indo-Pacific](/source/Indo-Pacific) region.<ref name="Hartog">{{cite journal |author=J.
