Title: Threadfin morphology
Description: Polynemidae is a family commonly known as threadfins. There are 42 extant species distributed in eight genera. Those fishes are globally distributed marine epibenthic animals, inhabiting sandy or muddy bottoms of turbid shallow waters (not exceeding 150 meters of depth). Their pectoral girdle is unique and highly modified, with a dorsal portion representing an unmodified fin and a ventral portion with elongate rays modified into tactile filaments, which they use to search for food, for example. The illustration depicts a polynemid general body, represented by Polydactylus virginicus and anatomical structures as follow: mandibular arch (Polynemus paradiseus), hyopalatine arch (Galeoides decadactylus), and Pectoral girdle (Pentanemus quinquarius).
