Lampreys and hagfishes are the only jawless vertebrates to survive today. They both have a round mouth and for this reason are often referred to as cyclostomes. They are the most primitive of the vertebrates. By primitive, a biologist means that they are the least changed from the first vertebrates.1  They have no paired pectoral (shoulder) or pelvic (hip) fins. 2  Their notochord persists for life, never being completely replaced by a backbone even in the lampreys.3  They have no scales.y primitive, a biologist means that they are the least changed from the first vertebrates. 1  They have no paired pectoral (shoulder) or pelvic (hip) fins. 2  Their notochord persists for life, never being completely replaced by a backbone even in the lampreys. 3  They have no scales.
Prosimians retain relatively primitive primate characteristics. Unlike simians (monkeys, apes and hominids), prosimians' brains are not exceptionally large compared to other mammals. Most have wet, dog-like noses, except for tarsiers. Tarsiers in fact are more closely related to simians than to the other prosimians.hey are primitive in the sense that they retain characteristics of the very first primates from millions of years ago. Prosimians include lemurs, lorises, galagos and tarsiers. Within simians, the next most primitive group is the new world monkeys.
