Salvelinus leucomaenis, the whitespotted char, is an East Asian trout in the genus Salvelinus, called iwana in Japanese. Both landlocked and ocean-run forms occur. The landlocked form typically grows up to 35 cm (1 ft 2 in), and prefers low-temperature streams. The seagoing fish typically grows to 70 cm (28 in) long. The largest reported specimen was 120 cm (3 ft 11 in) long and the oldest was nine years old.
