简单描述
型态特徵 | 形态测量图
Upper surface disk is densely freckled with small dark brown or pale brown and whitish spots, not arranged in rosettes (Ref. 7251). Spots on tail grouped in form about five or six prominent bars. Light and dark spots on dorsal and caudal fin. Lower surface whitish (Ref. 6902).
上表皮圆盘是厚密地散布着小的深褐色或者白褐色而微白色的斑点, 不排列成毛簇.(参考文献 7251) 在尾部上的斑点聚集了形式大约五或六条突出的横带。 在背鳍与尾鳍鳍上的淡色与深色的斑点。 下表面微白色的.(参考文献 6902)
Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205).
卵生的.(参考文献 50449) 卵在贝壳上有像触角一样的突出。 (参考文献 205)
