Corolla ovata
(Quoy & Gaimard, 1833)
 
Corolla ovata
Maximum size:

Identification:  Similar in size to Corolla spectabilis, this species is transparent with a broad swimming plate reticulated with bands of muscle fibers. It possesses a gelatinous, internal pseudoconch instead of an external calcareous shell. Mucous glands can be seen along the lateral edges of the plate. Mature animals are similar in general form to Corolla spectabilis but are covered with small, even white tubercles. Young animals appear more globular with proportionately larger tubercles.

Natural history:  Corolla ovata is a pelagic species that is rarely seen at night in off-shore waters.

Distribution:  Big Island: circumglobal.

Taxonomic notes:  It was first recorded in Hawaii off the Kona Coast of the Big Island by Keri Wilk on March 15, 2011.
