Northern Lampreys (Family Petromyzontidae)Observer
taxonomiqueDescription
Did not have prominent teeth, might be Alaska brook lamprey? Appears non-parasitic, and has beige patch on head. Threespine stickleback beside it.
Originally thought that might be Arctic lamprey (Lethenteron camtschaticum), as seen in drawing, but I think it's too small and very clearly not parasitic.

A juvenile found in an off-channel stream next to the Sacramento River. Many juveniles - which I assume were this species - were found in large muck filled pipe submerged in the stream.
