Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔魚
Spawn in the calcareous deposits of colonies of the polychaeta, Salmacinasp. which makes them more of 'cavity spawners' than 'spawners in live vertebrate' (Ref. 34819, 26281).西北太平洋: Karaginskiy 與指揮官島，白令海到鄂霍次克海與日本海洋; 一個記錄來自阿拉斯加灣西部。
