General information
The Mediterranean Sea Cucumber, Holothuria tubulosa, is a species of sea cucumber found in the Mediterranean Sea and parts of the Atlantic Ocean. It is known for its elongated, tubular body and leathery skin, which is usually dark with lighter tubercles. This echinoderm is an important part of the marine ecosystem, as it helps recycle nutrients by breaking down detritus and other organic matter.

Care
In the aquarium, Holothuria tubulosa requires a large tank with a deep sand bed and plenty of live rock to provide hiding places and surfaces for grazing. They are sensitive to changes in water quality, so stable conditions and excellent filtration are crucial. It's important to note that they can release toxins when stressed, which can be harmful to tank inhabitants.
Reproduction
Reproduction in Holothuria tubulosa typically involves spawning, where males and females release sperm and eggs into the water column. In an aquarium setting, breeding is rare, but if conditions are ideal, it is possible to observe spawning behavior.
Habitat
This species is commonly found on sandy and muddy bottoms, seagrass beds, and rocky substrates. They are often seen partially buried in the substrate with only their feeding tentacles exposed. In the wild, they can be found at depths ranging from shallow waters to about 100 meters.
