Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 25.0 cm TL male/unsexed; (Ref. 100471)
Maximum length is based on data from Marshall Islands (Ref. 100471). Found in coral reefs at depths of 10 to 20 m (Ref. 866). Derives a potent chemical defense from Halichondria sp., a sponge that it eats. It displays a spectacular swimming response - it throws its body into sweeping dorsoventral flexions creating synchronous undulations through its broad and vividly patterned red and white mantle (Ref. 100471). Eggs are deposited as coiled rosettes on rocks and coral rubble (Ref. 100471).
