Comments: The depth occupied by this species is unknown as most material were collected in fish markets, but probably mainly coastal.  A 69.5 cm DW adult male  weighed ca 12 kg.  Size at birth apparently variable;  83.0 cm DW female delivered a full term embryo  with small umbilical scar; however, other retained specimens, 26.1 cm DW still had a substantial yolk sac, while in another 19.3 cm DW  specimen the umbilical scar was barely visible.  All these young specimens have large mid-scapular tubercles and well-developed denticles over most of the dorsal disc; a small embryo with yolk sac (16.5 cm DW) had prominent mid-scapular tubercles, but other denticles are just starting to form on the disc (Ref. 84288).
