Description

Cyclocoeloma tuberculata is a small size spider crab, its carapace reach an average length of 45mm from the rostral area to posterior tip.[1] The back side of the 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's shape on a living animal because it's covered with anemones. The four ambulacry, when not too much decorated, are creamy color with brown bands. In the majids, the decoration is fixed on the carapace and legs via hooked hairs.[2] The 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. tuberculata fixes sea anemones of the family Discosomatidae to its carapace, and soft corals of the family Xeniidae to its legs.[3]

Distribution

Cyclocoeloma tuberculata is widespread throughout the tropical waters of the central Indo-Pacific region.[3]

gollark: Which one?
gollark: I mostly meant that it is quite complex to make and if you want nicer ones you need to throw even more industry at it.
gollark: At some point you probably hit physical limits and have to expand *slower*, but you aren't forced to stop.
gollark: Sure it is. Just expand more. The universe is quite large.
gollark: The smartphone you're probably sending this from is the product of hundreds of billions of currency units of development and capital investment and probably at least 50 countries worth of supply chain.
