Mastigoteuthis danae (Joubin, 1933)

Michael Vecchione and Richard E. Young
Containing group: Mastigoteuthidae


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, apparently are paralarval.

This description is taken from Joubin (1933). M. danae is known only from paralarvae and may represent the young stage of a known species.


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.

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
