(C) - Homocercal where the fin usually appears superficially symmetric but in fact the vertebrae extend for a very short distance into the upper lobe of the fin. Homocercal caudal fins can, however, also appear asymmetric (e.g. blue flying fish). Most modern fishes have a homocercal tail. These come in a variety of shapes, and can appear:
Most fish have a homocercal tail, but it can be expressed in a variety of shapes. The tail fin can be rounded at the end, truncated (almost vertical edge, as in salmon), forked (ending in two prongs), emarginate (with a slight inward curve), or continuous (dorsal, caudal, and anal fins attached, as in eels).
The caudal fin is homocercal, ... and locomotion is generally provided by a lateral undulation of the hindmost part of the trunk and the tail, propelling the fish ...
These fish also have eight anal fin rays on the tail fin, which is a forked [4] version of a homocercal tail. The dorsal fin lies behind the middle of the body. The dorsal fin lies behind the middle of the body.
The white sucker is a long, round-bodied fish with a dark green, grey, copper, brown, or black back and sides and a light underbelly. The fish also has typical features of primitive Cypriniformes fishes, such as a homocercal tail, cycloid scales, and dorsal, pectoral, and pelvic fin rays. [5]
It possesses a pair of pectoral fins, pelvic fins in the ventral and abdominal positions, which all are white, yellow, or silver. No adipose fin can be found after the dorsal fin on its back. The caudal fin or tail fin is notched and homocercal. This means that the tail has two lobes that are symmetrical.
Hoplopteryx has a dorsal fin supported by nine unjointed, bony rays, deeply forked, homocercal tail, a moderately developed anal fin, and a pelvic fin located well forward. The snout is quite short, the eyes fairly large, and both jaws of the upturned mouth hold small teeth .
It is a slender, elongated fish which has a small mouth with long extensions of both jaws forming a beak with the extension of the lower jaw being slightly longer than that of the upper jaw, the dorsal and anal fins are set far back on the body and have short bases, each is followed by 5-7 finlets between them and the deeply forked homocercal tail.
