生物學特性     字彙 (例如 epibenthic)

Facultative air-breathing (Ref. 126274); Found among branches of Stylophora mordax and certain Acropora corals (Ref. 9710). It never ventures outside the confines of the coral head where it swims between the branches foraging for other coral-dwelling types (Ref. 275). Anterolateral glandular groove with venom gland; at least in dorsal-fin spines (Ref. 57406).

發現於 Stylophora mordax 與特定的 Acropora 珊瑚的分支中了。 (參考文獻 9710) 它從不冒險外出至珊瑚頂部的疆界在那裡它在珊瑚枝之間游動覓食其他的棲息於珊瑚的類型.(參考文獻 275)
