Echinoteuthis danaeMichael Vecchione and Richard E. Young
Joubin (1933) collected 18 young squid of this species but based his description on three specimens, 61 (arm tip to tail), 45 and 17 mm (tentacle tip to tail). All specimens, in spite of the rather large size, these are paralarvae that lack most subadult characteristics.

- large tubercules in advanced paralarvae.
- a fin that is longer than wide.
- Arm suckers without teeth.
- Stalk about 2 mm in length and slender.
- Club enlarged in diameter, ca. 7 mm long.
- Club tip slender, ca. 3 mm long, with sucker buds.
- Funnel pocket unknown.
- Funnel pocket unknown.
- Funnel locking-apparatus
- Funnel locking-apparatus with a very large tragus and a distinct antitragus.
- Mantle and Skin
- Mantle and other skin, except fins, covered with small, cartilagenous tubercules.
- Tubercules absent from a 17 mm total length specimen.
- Fins longer than broad.
- Long tail present in small paralarvae but nearly absent in large paralarvae.
- Photophores absent.
- Few chromatophores present.

This description is taken from Joubin (1933). E. danae is known only from paralarvae and may represent the young stage of a known species, perhaps E. atlantica.
Type locality: North Atlantic; 34°40'N, 33°16'W, SE of the Azores; 16°03'N, 62°29'W near the Antilles; 30°51'N, 21°00'W east of the Canary Islands.
Salcedo-Vargas (1997) described four specimens (15-30 mm ML) from off Somalia, western Indian Ocean.
