Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm ?, range 30 - ? cm
Max length : 29.5 cm TL 雄魚/尚未辨別雌雄; (Ref. 106604)
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).
棲息於上層大陸斜坡與島嶼斜坡。 棲息於砂質底部了。 (參考文獻 26340) 卵胎生的有四個到 5 幼魚在一胎。
