Thuridilla carlsoni
Gosliner, 1995
 
Thuridilla carlsoni
Maximum size:  25 mm.

Identification:  This is a relatively cryptic species with low parapodia that meet at the midline without major folds. It may be distinguished by the "leopard-like" pattern of green spots and peach colored marginal band on its parapodia as well as the lime-green veins on the interior of its parapodia.

Natural history:  Thuridilla carlsoni is a common plakobranchid found on shallow rocky bottoms. It occurs in protected to moderately exposed locations at depths of 1-3 m (3-10 ft). Mature animals are diurnally active. The egg mass is a moderately to tightly coiled, cream spiral. A variable number of cream to pale orange longitudinal lines of superficial pigment may be present on the ribbon (usually visible only under magnification). The eggs hatch in about six days in the laboratory.

Distribution:  Big Island, Maui, Oahu and Kauai: widely distributed in the western & central Pacific.

Taxonomic notes:  It was first recorded in Hawaii from Oahu by Scott Johnson in the 1980s and was named after naturalist Clay Carlson who first found the species in Guam.
