Comments: The larger individuals of this species were collected at greater depth than smaller specimens, suggesting a positive relationship between size and depth, as has been observed in <i>E. princeps</i>.  The largest paratype (51.5 cm TL) contains five ova ranging from 25.6 to 34.2 mm, with no embryos apparent. The immature male paratype has claspers at the earliest stage of development, suggesting that maturity for males is attained at a greater size.  Viviparous with litter sizes apparently consist of at least 5 pups with post-partum lengths less than 177 mm TL (Ref. 106129).
