Eel No Frames Navigation Info Gigantic carnivorous fish belonging to the Anguilliformes order, which contains about 20 families, including the Moray. Eels are one of the hardiest species of any fish, and they absolutely thrive in cold, dark waters as voracious predators and scavengers. Giant eels have been measured upwards to 12 ft.
Many people believe that sea serpent sightings are the result of overgrown giant eels.
To support this theory, we have the case of a 6 ft long leptocephalus, or eel larvae, collected by the research vessel Dana in 1930. A normal leptocephalus is only 3 inches long. This ratio would make the adult of the giant larvae well over 100 ft in length. Tales of monster sized and man-eating eels have been around for centuries. In ancient Rome, rulers like Nero were said to throw disobedient servants into pits filled with hungry morays.
