Chlamydoselachoidei
Quick Summary
The suborder Chlamydoselachoidei includes sharks with a genus (Chlamydoselachus) that comprises sharks with diplospondylic vertebrae. This suborder includes the frilled shark (Chlamydoselachus anguineus), an eel-shaped shark found in deep waters. Frilled sharks have six pairs of gill slits with broad, frilled margins and a terminal mouth. The classification of these sharks can be complex, with some sources placing them in the suborder Notidanoidea alongside the Hexanchidae family, while others isolate them in their own suborder.12
