grasping end-organs. In adult males, the arms are all sexually modified in some way. The first pair becomes elongated and thicker, with swollen midportions and expanded protective membranes. The second pair has elongated and swollen tips, with reduced protective membranes. The third and fourth pairs all have slender whip-like tips. The suckers on the tips of the second pair have swollen collars and possess small pointed teeth around their entire margin, while the rest of the suckers on all the arms have small rounded or triangular teeth on the distal and lateral rims. The mid-arm and basal suckers of the third and fourth pairs also have swollen collars and greatly reduced openings.

small with developing photophores visible. They are slightly flattened dorsoventrally and mounted on short thick stalks. The arms are mere stubs, with lengths of 0.8 to 1.4 mm (0.031 to 0.055 in) when they reach mantle lengths of 8 to 9 mm (0.31 to 0.35 in). In contrast, the tentacles are very long and thick but without an expanded club. Four rows of suckers extend from the club to almost the base of the stalks. The mantle, head, arms, and tentacles are covered with relatively large widely spaced chromatophores.

They are arranged into concentric circles on the bloated mantle, confusing predators as to the location of the eyes. If the threat still does not go away, its last resort is to again eject ink. However, the ink is not released, instead it is retained inside the now spherical mantle cavity. The squid thus becomes a completely opaque black ball. 58: 424:. One of the photophores is oval-shaped and small, located at the upper part near the lens of each eye. The other two are concentric and located at the sides and bottom of the eyeball. One of them is very narrow and curves halfway around the lens.; the other is very large and crescent-shaped, straddling half of the bottom surface of the eyeball. 738:, hence the name. In this posture, they rotate around their spindle-shaped digestive glands, the only internal organs of the squid clearly visible through their mostly transparent bodies. Regardless of the direction their heads or mantles are facing, the digestive glands are always kept oriented vertically. 475:

The paralarvae develop the characteristic tubercle at the funnel-mantle fusion once they reach the mantle lengths between 30 and 60 mm (1.2 and 2.4 in). They enter the subadult stage once the eyes lose their stalks, becoming sessile, at sizes between 75 and 95 mm (3.0 and 3.7 in).

In subadults of both sexes and mature females, the basal and mid-arm suckers are usually smooth, though the small terminal suckers possess six to ten short triangular teeth on the distal and lateral rims. About 6 to 9% of the tips of all the arms of subadult and adult females are also modified into

tubercle is present at the mantle margins, though rarely it may be absent. The fins are long and narrow, starting at about 40 to 60% of the length of the mantle, far from where the body is the widest. They extend past the rear tip of the body, fuse with each other at the middle, and end with a pair

The first step is to turn its fins and gladius inside out. This is followed by the head and arms being inverted into the mantle cavity. Then the mantle is filled with seawater, turning them perfectly spherical. The tentacles are the last to be retracted. At this point the
