Extremly long rostral saw (more than 30% of total body length), with barbels. Lateral teeth on the saw, about 13 to 14 on each side. Two dorsal fins. Origin of first dorsal fin about opposite of free rear tips of pectoral fins.
Western Atlantic: Bahamas, Cuba and southern Florida.
Little-known species. Lives preferably in deeper water over the continental and insular slopes. On or near the bottom at depths between 600 m and 900 m.
Maximum total length about 80 cm, average size between 50 cm and 70 cm.
Probably aplacental viviparous (ovoviviparous).
Similar to other sawsharks (but none live in the same area). Not to be confused with sawfishes, which are rays. Sawfishes have their gill slits on the underside of their bodies, and the barbels are missing, too.
