Cycliophora

Containing group: Bilateria

Introduction

Cycliophorans live commensally on the mouthparts of lobsters of the family Nephropidae. The three known hosts are the American lobster Homarus americanus, the Norway lobster Nephrops norvegicus, and the European lobster Homarus gammarus (Obst et al. 2005).

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.
