With many eels "growing" from the sea floor, they look like garden plants—hence their name. Eels are snake-like fish that lack scales. There are around 800 species, ranging from some kinds just a few centimetres in length to the 3-metre (10-foot) giant moray. They have long, thin bodies with narrow dorsal fins that do not stick out from their bodies like those of other fish. Eels swim in a wave-like motion, called undulatory movement, that pulls their bodies into an S-shape (snakes move across land in a similar way). Eels live worldwide in oceans and rivers. Their young are called elvers.
Conger eel, worldwide up to 3 m (10 ft) long. Conger eels, which grow up to 3 metres (10 feet) long are bottom-feeders. They will often hole up in a wreck or rough ground and dart out to capture other, smaller fish in their powerful, teeth-lined jaws. Congers are mostly nocturnal feeders, but in darker depths of 20 metres (65 feet) or more they will seek prey at any time.
Moray eels have a second set of jaws in their throats. Called pharyngeal jaws, these are also lined with teeth. When feeding,...Read More >>Moray eels have a second set of jaws in their throats. Called pharyngeal jaws, these are also lined with teeth. When feeding, morays launch these jaws into their mouth. These grab the prey and take it into the throat.
Eels were not known to be fish until the late 18th century.
