Lungfish
Just because the water dries up is no reason for lungfish to sell life short. When the water begins to dry up, the West African Lungfish Protopterus aethiopicus, burrows in mud and goes into a dormant state called estivation. While it's hot and dry outside, the lungfish stays inside it's waterproof cocoon of mucous and mud, connected by a small air tube to the surface until it's time to come out months to years later. Estivation differs from hibernation in that ...
Lungfish are relatively long-lived. Austrialian lungfish Neoceratodus forsteri, such as "Granddad" at the Shedd Aquarium in Chicago and "Methuselah" at the Steinhart Aquarium in San Francisco are the oldest documented fish kept in aquaria.
Other fishes such as goldfish (Carassius auratus) and carp (Cyprinus carpio) routinely live for decades. For the Lake Sturgeon (Acipenser Fulvescens), "the typical life-span of lake sturgeon is 55 years for males and 80-150 years for females." [x]
