Blue Dragon Nudibranch, Serpent Pteraeolida

Pteraeolidia ianthina

Description:

"Variable in color ranging from pure white in juveniles to brown, green or blue. Color depends on the amount of symbiotic zooxanthella living in the tissues. Always has 2 - 6 mauve bands around the oral tentacle" Source:- Neville Coleman's Marine Life eGuide Pteraeolidia ianthina, commonly known as the 'Blue Dragon' by divers in eastern Australia, is one of a group of remarkable aeolid nudibranchs which are way ahead of man in harnessing solar energy. Pteraeolidia has evolved a method of capturing and farming microscopic plants (zooxanthellae) in its own body. The plants flourish in this protected environment and as they convert the sun's energy into sugars, they pass a significant proportion on to the nudibranch for its own use. Source - Sea Slug forum

Notes:

Spotted at Pinnacle, Ligpo Island at a depth of about 6 m.
