Anguilliformes - Sidhat - 鰻鱺目 - Eel Eels (Anguilliformes; pronounced /æŋˌɡwɪlɨˈfɔrmiːz/) are an order of fish, which consists of four suborders, 19 families, 110 genera and approximately 800 species. Most eels are predators. The term "eel" is also used for some other similarly shaped fish, such as electric eels and spiny eels, but these are not members of the Anguilliformes order. DescriptionEels are elongated fishes, ranging in length from 5 centimetres (2.0 in) in the one-jawed eel (Monognathus ahlstromi) to 4 metres (13 ft) in the slender giant moray. Adults range in weight from 30 grams to well over 25 kilograms. They possess no pelvic fins, and many species also lack pectoral fins. The dorsal and anal fins are fused with the caudal or tail fin, forming a single ribbon running along much of the length of the animal. Most eels live in the shallow waters of the ocean and burrow into sand, mud, among rocks, or in cracks found in coral reefs. A majority of eel species are nocturnal, and thus are rarely seen. Sometimes, they are seen living together in holes, or "eel pits". Some species of eels also live in deeper water on the continental shelves and over the slopes deep as 4,000 metres (13,000 ft). Only members of the Anguillidae family regularly inhabit fresh water, but they too return to the sea to breed. Eels begin life as flat and transparent larvae, or leptocephali. Eel larvae drift in the surface waters of the sea feeding on marine snow, small particles that float in the water. Eel larvae then metamorphose into glass eels and then become elvers before finally seeking out their juvenile and adult habitats. |
| Anguilliformes - Sidhat - 鰻鱺目 - Eel Ordo Anguilliformes  Elongate fishes with pelvic fins and pelvic girdle absent or reduced. Ikan memanjang dengan sirip perut dan korset perut tidak ada atau berkurang. The paired pelvic or ventral fins are located ventrally below the pectoral fins. They are homologous to the hindlimbs of tetrapods. The pelvic fin assists the fish in going up or down through the water, turning sharply, and stopping quickly.  Pelvic fin ray: each of the bones forming the fin beneath the pelvic girdle. Pelvic girdle: set of bones forming the pelvis. |
