生物學特性     字彙 (例如 epibenthic)

Found on the continental shelf and littoral areas (Ref. 247).A sluggish and inactive species that buries itself in sand or mud (Ref. 247). Also found around rocks, heads of submarine canyons, and sometimes near kelp forests (Ref. 247). Feeds on bottom and epibenthic fishes, including croakers, California halibut, and squid (Ref. 247). Ovoviviparous (Ref. 50449). Can whip up its head and snap very quickly when touched, provoked, harassed, or speared, and can inflict painful lacerations (Ref. 247).

棲息於大陸棚與沿海地區區域了。 (參考文獻 247)掩藏於沙或泥中的一個緩動性而不活躍的種.(參考文獻 247) 也岩石,海中峽谷的頭部周圍發現, 與有時在海藻林的附近.(參考文獻 247) 吃底部而淺海底棲魚,包括嗄嗄叫, 加州大比目魚 , 與烏賊.(參考文獻 247) 卵胎生的.(參考文獻 50449) 能突然抬起它的頭部而且非常快地猛咬當接觸,激怒,被攻擊, 或獵殺了, 而且能施放令人痛苦的撕裂.(參考文獻 247)
