The lampreys (Petromyzontiformes), one of the two surviving groups of agnathan (jawless)
vertebrates, currently consist of 41 recognized species. This group has an antitropical …

Forty-four species of lampreys (Petromyzontidae) are currently recognized:(a) nine species

The development of a movable jaw is one of the most important transitions in the
evolutionary history of animals. 1 Jawed vertebrates rapidly diversified after appearing …

Fishes are the longest persisting living vertebrates and as such, display an incredible array
of diversity. Variation in the tail, or caudal fin, is often a reflection of a fish's environment, and …

Despite their highly conserved body plan and larval stage, adult life history type in lampreys
diverges on two main axes related to migration and feeding. Of the 41–45 recognized …

Some lamprey genera include forms that have significantly different life cycles (the most well
known are the “anadromous” and “resident,” or the “parasitic” and “nonparasitic” forms). The …
