Common name: Sea Cucumber

Holothuria is a genus of sea cucumbers commonly found in reef environments. These echinoderms are known for their elongated bodies and leathery skin. They play a crucial role in the ecosystem by recycling nutrients as they process organic matter in the sand. In the aquarium, they can help maintain a clean substrate but require a mature system with plenty of detritus to thrive. Some species may release toxins when stressed, so careful handling and acclimation are essential.
