Maturity: Lm ?, range 30 - ? cm

Inhabits the upper continental and insular slopes. Found on sandy bottoms (Ref. 26340). Ovoviviparous with 4 to 5 young in a litter. Maximum size reported in Ref. 106604 after Bigelow & Schroeder (1948). Maximum sizes of 31.5 cm precaudal length (Longley & Hildebrand,
1941) and 50.0 cm TL (Ref. 247) probably refer to the subsequently described and very similar E. robinsi, which attains a greater maximum size according to Schofield & Burgess (1997) (Ref. 106604).
栖息于上层大陆斜坡与岛屿斜坡。 栖息于砂质底部了。 (参考文献 26340) 卵胎生的有四个到 5 幼鱼在一胎。
Ovoviviparous with 4 to 5 young in a litter. Size at birth about 9 cm (Ref. 247). Distinct pairing with embrace (Ref. 205).西大西洋: 维吉尼亚到佛罗里达南部 (美国) ，古巴，百慕达群岛与圣 Kitts;(参考文献 247) 包括巴西。 (参考文献 53443) 东大西洋.(参考文献 26340)
