Pelvic fin - Wikipedia
Pelvic fins or ventral fins are paired fins located on the ventral (belly) surface of fish, and are the lower of the only two sets of paired fins (the other being the laterally positioned pectoral fins).
Fish fin - Wikipedia
The pelvic fin assists the fish in going up or down through the water, turning sharply, and stopping quickly. In gobies, the pelvic fins are often fused into a single sucker disk. This can be used to attach to objects [1] Pelvic fins can take many positions along the ventral surface of the fish.

Fish have two sets of paired fins: pectoral and pelvic (Fig 4.25). The pectoral fins are vertical and are located on the sides of the fish, usually just past the operculum (Table 4.7). Pectoral fins are similar to human arms, which are found near the pectoral muscles.
Pelvic Fin - an overview | ScienceDirect Topics
Pelvic fins, although little studied, are of great interest as they are one of the most morphologically plastic structures within the fishes. The function of the pelvic fins is as variable as their morphology between fish. They are used in swimming as an aerofoil, brake, propulsor, and rudder, for ground walking, and for hovering.

2014年4月11日 · The pelvic fins are paired fins found on the ventral (bottom) side of fish. In teleost (bony) fishes, pelvic fins placement gives some indication of evolution. For more basal groups, the pelvic fins are located at mid-body in the abdominal region.

2016年12月15日 · The musculoskeletal anatomy of the pelvic fin in bichirs – genus Polypterus – is a key piece of evidence for reconstructing the evolution of complex pelvic appendicular musculature in gnathostomes as a whole and osteichthyans (bony fishes + tetrapods) in particular, and for understanding the evolutionary and functional relationships between ...
Pelvic fins in teleosts: structure, function and evolution
The pelvic fins of teleosts are paired appendages that are considered to be homologous to the hind limbs of tetrapods. Because they are less important for swimming, their morphology and function can be flexibly modified, and such modifications have probably facilitated the adaptations of teleosts to various environments.
