Sea Urchins, Starfish, and Sea Cucumbers
1995Abstract Echinoderms (Phylum Echinodermata), which include sea urchins, starfish, brittle stars, and sea cucumbers, have a distinctive radial pattern which may take the form of five arms radiating from a central disc or a more globular or cylindrical shape, again with structures arranged in five rays (or multiples of five) (Fig. 12.1).

Cytotoxic Triterpene Glycosides from Sea Cucumbers
2014The class Holothuroidea (sea cucumbers) belonging to the phylum Echinodermata is characterized by the production of triterpene glycosides with sulfate groups attached to the monosaccharide residues in a great majority of the saponins isolated so far. Due to their toxicity and membranotropic action, these polar compounds have attracted the attention of ...

Swimming, once considered a surprising and unusual feat for sea cucumbers, which are representatives of the phylum Echinodermata typically characterized by a semi-rigid calcareous skeleton, is emerging as a relatively common feature in species living in the deep sea.

Antifungal Steroid Glycoside from Sea Cucumber
Science, 1969An antifungal steroid glycoside, holotoxin, has been isolated from the sea cucumber Stichopus japonicus (Selenka). In vitro, it exhibits high activity against various fungi, including vegetable pathogens, but has scarcely any activity against Gram-positive and Gram-negative bacteria and mycobacteria in vitro.

Sea cucumbers symmetry (Echinodermata: Holothuroidea)
Paleontological Journal, 2014The types of symmetry that are characteristic for the class Holothuroidea and reflect different stages in the evolution of this group of echinoderms and the role of paedomorphosis in its origin are analyzed. A hypothesis is proposed to explain the distinctive structure of the water vessel (ambulacral) system of sea cucumbers and the origin of the class
