The golden volute, Iredalina mirabilis, is a species of rare, large, deepwater sea snail, a marine gastropod mollusc in the family Volutidae, the volutes. This is the only species in the genus; in other words, Iredalina is a monotypic genus. Distribution This species is endemic to New Zealand. It is found off the east coast. Habitat This volute lives at depths of between 180 and 700 m, although empty shells are sometimes found in shallower water, presumably carried there by hermit crabs. Shell description This rare shell is highly prized by collectors. The shell height is up to 140 mm, and the width up to 48 mm.
