Anguilliformity is a morphological pattern in fishes, named for and typified by the eels. Anguilliform fish have a long, slender body, and travel by anguilliform motion. The caudal fin is often emphasized, with the other fins reduced, absent, or fused with the caudal fin. [1] .

In addition to their eel-like bodies, anguilliform species have widely varying coloration that ranges from black or dark gray in deep-sea species to rich colors and complex patterns in tropical reef species. Adult sizes range from about 4 in (10 cm) to 11.5 ft (3.5 m), as in the moray species Thyrsoidea macrura.

When an elongated fish such as an eel swims, its entire body, which is flexible throughout its complete length, moves in a series of sinuous waves passing from head to tail. In this type of movement, which is called anguilliform (eel-like) locomotion, the waves cause each segment of the body to oscillate laterally across the axis of movement ...

Anguilliform swimming is characterized by undulations of the body and caudal fin. Fish species using anguilliform locomotion typically have very flexible and elongate bodies that can be bent into at least half of a sine wave, when viewed dorsally.

The major forms of locomotion in fish are: Anguilliform, in which a wave passes evenly along a long slender body; Sub-carangiform, in which the wave increases quickly in amplitude towards the tail; Carangiform, in which the wave is concentrated near the tail, which oscillates rapidly;

The Anguillidae are a family of ray-finned fish that contains the freshwater eels. All the extant species and six subspecies in this family are in the genus Anguilla, and are elongated fish of snake-like bodies, with long dorsal, caudal and anal fins forming a continuous fringe.

2024年9月28日 · Anguilliform Locomotion: This type involves a serpentine movement, resembling that of a crawling snake. The propulsion in anguilliform locomotion is primarily generated by the pressure exerted by the fish’s body against the surrounding …

2024年12月20日 · eel, (order Anguilliformes), any of more than 800 species of teleost fishes characterized by elongate wormlike bodies. Anguilliforms include the common freshwater eels as well as the voracious marine morays.

The total share of fish species of these six orders is about 66% of all known to day representatives of the ichthyofauna at depths deeper than 1000 m. The most diverse families by number of species are: Zoarcidae (33 species, 14%), Liparidae (26 species, 11%) and Myctophidae (22 species, 9%).

2020年4月6日 · In this paper, we explore anguilliform aquatic locomotion in fishes using physical models that are simple in shape and to control, but that are three-dimensional and represent a reasonable approximation of an elongate eel-like swimming fish. Anguilliform locomotion in fishes is common to many elongate species and is
