简单描述
型态特徵 | 形态测量图
Upper surface of disc is largely smooth except around the eyes. Pale coffee brown except for a translucent area either side of rostral cartilage. Pale areas around the mouth, gill openings and tail (Ref. 6902).
体盘的上表面非常平滑除了眼睛四周以外。 灰白的褐色除了半透明的区域嘴软骨组织的任一侧边。 灰白的环绕着嘴巴，鳃裂与尾部的区域.(参考文献 6902)
Solitary (Ref. 26340). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205).
