Common name: Decorator Crabs
The genus Cyclocoeloma is a fascinating group of crabs commonly known as Decorator Crabs. These crabs are part of the family Epialtidae, also known as Decorator Crabs, and are renowned for their unique behavior of adorning themselves with materials from their environment. This behavior serves as a form of camouflage, allowing them to blend seamlessly into their surroundings to evade predators. Decorator Crabs will attach various items such as seaweed, sponges, and small pieces of coral to their shells using specialized hooked setae, which act like Velcro.
In the aquarium hobby, Decorator Crabs are appreciated for their interesting and interactive behavior. They are relatively easy to care for and can be a delightful addition to a reef or marine tank. However, aquarists should be mindful of their decorating habits, as they may pluck at corals or other invertebrates to use in their camouflage. Providing them with suitable materials, such as pieces of marine sponge or algae, can help mitigate this behavior.
Decorator Crabs are generally peaceful and can coexist with a variety of other marine species. However, they should be monitored in tanks with delicate corals or slow-moving invertebrates. They are omnivorous scavengers, feeding on detritus, algae, and any available organic matter, which makes them excellent members of a clean-up crew.
Scientifically, the genus Cyclocoeloma provides insight into the biological adaptations of marine crustaceans. Their decorating behavior is not just a survival strategy but also a fascinating example of animal behavior that has intrigued marine biologists for years. This genus highlights the complexity of interactions between marine species and their environments, making them a subject of interest both in the hobbyist community and scientific research.
