Description synthétique Morphologie | Morphométrie

Rayons mous dorsaux (Total): 3; Rayons mous anaux: 5 - 6; Vertèbres: 29 - 31. Amaralia oviraptor differs from its only congener, A. hypsiura, by having more dorsal-fin rays (3 vs. 2); by having a lateral contact between middle and posterior nuchal plates (vs. middle and posterior nuchal plates not contacting each other laterally); by having feeble serrations along the distal portion of the anterior margin of pectoral-fin spine (vs. absence of serrations along the anterior margin); and by its longer cleithral process (17.4-19.5 % of SL, mean 18.2 % vs. 14.0-17.2 % of SL, mean=15.5 %) (Ref. 111083).

Biologie     Glossaire (ex. epibenthic)
