Summary:
A large uniform dark chocolate-brown chimaera with deciduous skin and a relatively long tail. Although the first dorsal-fin spine is generally taller than the rest of the fin (hence the common name), it ranges in length 18-28% of body depth. Mature males have short, trifurcated claspers that are divided for the distal one-third of their length.
