The second dorsal fin also bears a spine in front and is over twice as large as the first in area, with the span between it and the first dorsal fin approximately equal to the distance between the snout tip and first gill slit. The anal fin is absent. The caudal fin is low and narrow, with an indistinct lower lobe and an upper lobe about as long as the head.
