Eight species of suckers occur in Florida, including two species of Carpiodes carpsuckers, the quillback and the highfin carpsucker. As their common name implies, these silvery, deep-bodied fish resemble common carp. However, both carpsuckers may be distinguished from carp by the absence of barbels, and lack of spines in dorsal and anal fins of the carpsuckers. In both carpsuckers, the mouth is situated on the underside of the head and the snout extends forward beyond the jaws; also, the first ray of the dorsal fin may be very long, forming an elevated filament. Quillback and highfin carpsuckers are very similar in appearance, but they may be separated by looking at the lower lip. The quillback does not have a nipple-like knob at the middle of the lower lip, while the highfin carpsucker has a small nipple at this location. Both carpsuckers may be distinguished from other Florida suckers by body shape. The carpsuckers have deep, slab-sided bodies, while our other suckers are more elongate or somewhat cylindrical in shape. Show us the dorsal fin (pic please) as the carpsucker has a different shaped dorsal fin Somebody go tell brett we need him! |
