Lamprey is a type of boneless blood-sucking fish, which can be distinguished by its long and tooth-filled mouth. This species does not have a jaw and has been around for more than 350 million years. Although this species can be found in many states, the discovery of two new species in California indicates that their distribution is broader there.

This research can help provide information about the population and distribution of species so that biologists can better protect those species. Forests are very important for local ecosystems and food chains. Fish larvae feed on algae and other organic matter in the water, which helps filter and clean it. Without those species, water quality will decrease.
