AMERICAN RIVER | Welp, this gives us a reason not go into the American River... Last week, the founder of the Facebook page American River Lost & Found caught video of this lamprey swimming in the American River. The original post says that this is only the second time he's seen this in 30 years. | ABC10

Lamprey 🩸 The Bizarrest Monster of the River! Prepare to be horrified! This isn't your average fish. Meet the lamprey, a prehistoric predator with a taste for blood. With a mouth that's a living nightmare and a feeding habit that's straight out of a horror movie, this creature is the stuff of nightmares. #lamprey #fish #wildlife #oceanlife #sealife | 1 Minute Animals
