This sign beside Lake Matheson describes the New Zealand longfin eel (Anguilla dieffenbachii), which are abundant in the lake. Nearly everything about this eel is remarkable. New Zealand's largest eel, it can grow to over 5 feet long and weigh more than 50 lbs. Some individuals have lived over 100 years.
Even more remarkable is its migration route. Near the end of their lives, they swim out to sea and then north to Tonga, nearly 2000 miles. There they spawn and the larvae then drift on oceanic currents until some of them are eventually carried 2000 miles back to New Zealand. There they transform into small eels and head upriver. During this juvenile phase they are excellent climbers and have been known to climb 140 feet up a near vertical surface.
