Coloration All Histioteuthidae have a brilliant coloration. The key hue, which is red or dark violet, is caused not only by the numerous chromatophores but also by the granulate pigment in the cutis. Pale violet specimens, like the large specimen of Calliteuthis ocellata, too, get their splendor from the numerous luminous organs which appear like jewels on the skin. According to V£rany, the organs of the live Histioteuthis gleam like pea

Pale violet specimens, like the large specimen of Calliteuthis ocellata, too, get their splendor from the numerous luminous organs which appear like jewels on the skin. According to V£rany, the organs of the live Histioteuthis gleam like pearls, with a blue margin and with a mirror with a mirror with a golden sheen anteriorly. This vivid coloration extends over the whole body except the fins, which are always paler. The tentacles, too, are generally less lightly colored than the arms. The inner surface of the arms is lighter, except for the sucker-bearing area surrounded by the protective membranes. The "sail" of Histioteuthis is intensively colored on the outside and inside. The outer side of the buccal membrane is also usually dark-violet. 123.
