    2. Ventral mantle shield extends anteriorly past base of arms.

      Figure. Ventral (left) and dorsal views (right) of N. pourtalesii, holotype. Photographs by R. Young.

  4. Fins
    1. Fins extend anteriorly beyond the dorsal mantle margin but do not reach the mantle margin posteriorly.

Comments

The holotype (NMNH 729734) presumably is a male judging from the arm sucker modifications. The mantle has not been cut open to verify the sex.

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.
