Tubular sea cucumber

Sea cucumber presenting an elongated and cylindrical body, commonly exhibiting a colouration in shades of brown or tan. The skin is rough and covered with small dermal papillae, while sclerites or dermal spicules provide structural rigidity. At one end of the body, there is the mouth surrounded by oral tentacles, and the anterior end may be narrower. This species inhabits sandy or muddy bottoms in marine environments, and morphological variability may exist within the species. For precise identification, it is recommended to consult specialised sources or seek guidance from experts in echinoderms.
