Mythology and literature record wels catfish of astounding proportions yet are to be proven scientifically. The typical size of the species is about 1.2–1.6 m (3.9–5.2 ft), and fish more than 2 m (6.6 ft) are rare. However, they are known to exceed 2.5 m (8.2 ft) in length and 100 kg (220 lb) in weight.

Such lengths are rare and unproven during the last century, but there is a somewhat credible report from the 19th ...
