Length at first maturity / Size / Weight / سن
بلوغ: Lm ? range ? - ? cm Max length : 25.0 cm TL جنس نر / بدون خواص جنسي; (مرجع 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).
Life cycle and mating behavior
