Introduction

H. ryukyuensis is described from two squid, one male (18 mm ML) and one female (17 mm ML), vomited by a captured fish (ruby snapper). It has some very unusual features and doesn't fit well into the genus Heteroteuthis. With more new species recently found in the subfamily, the generic boundaries have become increasingly hard to define.

The fish from which H. ryukyuensis came was caught off the northeast coast of Taiwan.

This page is a Tree of Life Branch Page.

Each ToL branch page provides a synopsis of the characteristics of a group of organisms representing a branch of the Tree of Life. The major distinction between a branch and a leaf of the Tree of Life is that each branch can be further subdivided into descendent branches, that is, 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.
