Lamprey are a lineage of boneless fish that is older than trees. Traditionally, lamprey species have been identified by morphology - that is, their visible features, such as teeth. However, this method can be unreliable because without bones, lampreys don't have many distinguishing features, and most of these don't develop until adulthood. Thus, significant conservation actions may be taken, or not taken, based on species designations that are … slippery.
