While filming juvenile salmonids, discovered a writhing nest of spawning lamprey at the mouth of a small tributary adjacent to Brooks Lake, Katmai National Park & Preserve, Alaska Peninsula

The lamprey (approximately 10-12) were very active, both actively and passively moving sediment whilst gyrating in a fairly tight group. Although small in size, they appear to be Pacific, not Arctic Lamprey due to greenish dorsal coloration and lack of dark splotch on posterior dorsal fin and tail. River Lamprey (Lampetra ayresii) are not found in this region of Alaska. After review footage in slow motion, was still unable to determine species ID through pattern of teeth: three large teeth on the supraoral bar and three sharp points on each of the central lateral tooth plates.

The mergansers here would dive beneath the water, then pop up with squirming eels in their beaks. Then the other mergansers (and sometimes gulls) would chase them around, trying to steal the eels. This observation is for the eel.

Possible big brown based on head shape but still not too sure. Was brought to me with the umbilical still attached.
Very dehydrated and took hourly feedings at the start, fed a goats milk formula mix, hair started to develop after the first week, and lived for about two weeks. Very little sleep was had for those two weeks.
