Key Identification Features
- During the larval stage, the dorsal fins are connected; after metamorphosis, they split into two distinct separate dorsal fins.
- This species is distinguished by three (or occasionally two) sharp teeth on the supraoral bar above the mouth, and three sharp points on each lateral plate.
- Smoked lamprey is a staple food, featured at many communal feasts.
- During this growth, the original dark longitudinal band on the body also begins to lighten, and is no longer distinct in more mature ammocoetes.
