Oh my goodness! Unless you are a Tree of Life developer, you really shouldn't be here. This page is part of our beta test site, where we develop new features for the ToL, often messing up a thing or two in the process. Please visit the official version of this page, which is available here.

Introduction

O. carriboea is known, with certainty, only from small juveniles. Like most (all?) young in this genus, it is found in the neuston of the surface waters, where it is often associated with the floating seaweed, Sargassum. It has a purplish dorsal surface and silvery to golden sides and ventrum.

Characteristics

Species characteristics change rapidly with growth. Insufficient information is available to distinguish this species from other species of Onykia when comparing only small juveniles.

Nomenclature

This is the type species of the genus. The type locality is the Gulf of Mexico and the Gulf Stream. Specimens of subadult Onykia from the Gulf of Mexico appear to be conspecific with O. robsoni (Kubodera, et al., 1998). Therefore, O. robsoni could ultimately prove to be a junior synonym of O. carriboea. However, detailed comparisons of specimens from their respective type localities are needed before this problem can be resolved. The problem is further complicated by the fact that the holotype of O. carriboea no longer exists (Sweeney and Roper, 1998).

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.
