Geographic Range [top]

Range Description:Iridoteuthis iris occurs in the open ocean near to the Hawaii Islands and Colahan and Kammu seamounts (Reid and Jereb 2005).  It has been captured at a variety of localities along the Hawaiian Archipelago from about 21 °N, 157 °W to about 32 °N, 177 °E. All captures are close to islands or seamounts and are from relatively shallow fishing depths (c. 150-300 m).

Habitat and Ecology [top]

Habitat and Ecology:Females attain a larger body size (up to 28mm in mantle length) compared to males (up to 24 mm in mantle length) (Reid and Jereb 2005). This is a pelagic species (Reid and Jereb 2005). Mature males have enlarged suckers on their third pair of arms (Norman 2003). Members of the subfamily Heteroteuthinae are free swimming in the open ocean (Norman 2003). Iridoteuthis iris appears to be a member of the mesopelagic boundary fauna occurring over bottom depths of less than 450 m (Young 1995).
