Dendrochirotid holothuroids; small, up to 40 mm long; mid-body arched dorsally in transverse section, flat ventrally; dorsal and lateral body covered with imbricating scales, usually macroscopically conspicuous, irregular in size and arrangement; scales decreasing in size ventro-laterally, orally and anally; lacking large oral valves; extensible oral cone, anterior to anteriordorsal to dorsal orientation; extensible anal cone, posterior to posterior-dorsal to dorsal orientation; tube feet dorsally and laterally in mid-body, pass through scales. Sole distinct, oval to elongate; discrete margin created by junction of small imbricating ventro-lateral scales with thinwalled, usually calcareous, sole that lacks scales; peripheral band of tube feet, may be discontinuous across the inter-radii anteriorly and posteriorly; peripheral tube ... : Published as part of O'Loughlin, P.
