Краткое описание
определительные ключи | морфология | морфометрия
Potamotrygon jabuti is distinguished by the following characters: marbled color pattern that undergoes remarkable change with growth as adults have elaborate designs of beige, golden to yellowish-orange spots or ocelli surrounded by a slender beige to golden mesh-like pattern, but neonates have simple, well-separated ocelli; a single to double row of tail thorns varying in their development; monognathic heterodonty with teeth of intermediate lateral rows of upper jaws larger and hexagonal; and two robust, more or less equally developed angular cartilages (Ref. 115937).
