The type species (C. muelleri) is restricted to the Arctic Ocean and far North Atlantic. Specimens from the Pacific, Indian Ocean and southern hemisphere, which have been referred to as the big-finned jellyhead or C. cf. muelleri, have recently been attributed to a separate species Cirroteuthis kirrilyae Verhoeff & O'Shea, 2025 (based on both morphological and molecular data).
