Caloria
sp. #3
 
Caloria sp. #3
Maximum size:  12 mm.

Identification:  This species is very similar to Caloria indica. However, it differs from it in having rhinophores with white tips and having a single white line extending posteriorly from the rhinophores onto the notum. Its body also tends to be translucent cream, rather than orange, and has a row of red lozenges on each side.

Natural history:  Caloria sp. #3 appears to be moderately common in highly protected to protected sites on Oahu but is rare elsewhere. It occurs at depths of as little as 1 m (3 ft) and is a diurnal species.

Distribution:  Big Island and Oahu: this color form is widely distributed in the Indo-Pacific.

Taxonomic notes:  This animal is usually listed as a color form of Caloria Indica (and was lumped with that species in Kay, 1979). However, there is little sign of intergrading between the two and substantial differences in habitat. So, we are treating it as different pending more work. There is also some question about which form should be called C. indica if they are split. It was first recorded in Hawaii at Magic Island, Oahu by Scott Johnson on Feb. 4, 1984. It's lumped with Caloria indica (under Caloria militaris) in Kay & Schoenberg-Dole, 1991 (but only the right animal in the photo is this species).
