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.
Damiani et al 2006: Temnospondyli :: (Capetus + (Euskelia + Limnarchia)) + (Edopoidea + *). i.e. Saharastega and Edopoids form a clade which is the sister group to all other Temnospondyls; in other words the most primitive or basal outshoot of the temnospondyl ancestry.ee also comments on early temnospondyl phylogeny. or Steyer et al. 2006: Steyer et al. 2006: Temnospondyli :: (Edopoidea + Eryops) + * Saharastega represents a primitive but not the most primitive form; Edopoids + Saharastega are a grade not a clade, and Saharastega is the sister group to the Edopoids and Eryopoids.
