Eyespot rasbora ventral area of the body between the operculum and the pelvic fins (corresponding roughly to the sac enclosing the alimentary canal). Under conditions of reflectied light, the fish sometimes displays a fine lateral band from the opeculum to the end of the caudal peduncle (Walker, 1971, p. 98) this being an olive-gold hue. The fins, with the exception of the dorsal fin, are hyaline, the relation of the pectoral and pelvic fins being typical of the ostariophysans (fishes possessing an auxiliary mechanism for detecting sound consisting of a set of internal bones called the Weberian Ossicles). In such fishes, the
Peduncle (botany) Peduncle (botany) In botany, a peduncle is a stem supporting an inflorescence, or after fecundation, an infructescence. The peduncle is a stem, usually green, though some peduncles are more or less florally colored or neutral in color, having no particular pigmentation. In some species, peduncles are leafless, though others bear small leaves, or even cataphylls, at nodes; such leaves generally may be regarded as bracts. The peduncle is the inflorescence base without flowers. When an unbranched peduncle has no obvious nodes, rises directly from a bulb or stem, and especially if it rises apparently directly from the ground, it commonly
