Description:
The distinctive features of this organism include well-defined eight costa and comb structures. Each rib is narrow, flat at the aboral end, and tapers orally, with eight combs along its length. The comb width narrows towards the oral end, following the rib’s decreasing width, with the last comb being notably narrow and bearing few cilia. The cilia are lengthy, united up to two-thirds of their length, and those in the upper combs are half the costa’s length, beating towards the mouth. The small, spherical, opaque statolith appears granular and is often obscured by sensory papillae, numbering twenty, which are long, slender, contractile, and capable of supple movements. The elliptical sensory region is surrounded by a semicircular ring of unpigmented papillae. The aboral sense organ, polar fields, and papillae-containing area can be retracted and extended, especially when the organism is agitated. The papillae and polar fields lack pigmentation. The two tentacles, with uniseriate branches decreasing in length towards the distal extremity, are long, highly contractile, and emerge and retract through a narrow mouth in the spacious tentacle sheath. The transparent sheath allows visibility of the tentacle root when pigmentation above it lightens.
