(Bigelow, 1911)
Description
Anterior nectophore [Eudoxoides spiralis ]: characteristically spirally twisted to the ridges. The ventral ridges unite closely to the apex. The divided mouth plate is long and pointed. The hydroecium is claw-shaped, and the thickened somatocyst extends to about half the nectophoral height.
Posterior nectophore: not developed.
Eudoxid [E.spiralis-eudox ]: the bract is roughly conical with two lightly serrated ridges and a wide, deep neck-shield. The phyllocyst is stout and long, reaching almost to the apex. The gonophore is characteristically twisted, its four ridges being lightly serrated.
Size
Anterior nectophore up to 12 mm in height; the bract is up to 4 mm in height.
Depth range
Epipelagic.
Distribution in the North Sea
Possibly in the northern North Sea; Eudoxoides spiralis has been collected a few times to the north-west of Scotland
World distribution
All Atlantic Ocean, although more often found in the warmer waters.
