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.

This tree diagram shows the relationships between several groups of organisms.

The root of the current tree connects the organisms featured in this tree to their containing group and the rest of the Tree of Life. The basal branching point in the tree represents the ancestor of the other groups in the tree. This ancestor diversified over time into several descendent subgroups, which are represented as internal nodes and terminal taxa to the right.

You can click on the root to travel down the Tree of Life all the way to the root of all Life, and you can click on the names of descendent subgroups to travel up the Tree of Life all the way to individual species.

Scientific Name Caprella sp.
Location 49 km W of San Jose, California, USA
Comments Skeleton Shrimp (Caprella sp.) were EVERYWHERE on the ostrich plume hydroids (Aglaophenia sp.), even out of the water. I was reading Between Pacific Tides the night before, and they mentioned Aglaophenia latirostris was a great habitat for pycnogonids, so I kept sifting and sifting through the hydroids (Minette, I even used my little net!), but alas, no sea spiders. Still, caprellids rock, so I was happy to find them instead.

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.
