Protoctista - Unicellular Eukaryotes

Welcome to the Xanthophyta page. These links are provided as additional information to go along with the topics covered on my website. At the time of this posting, the links are all in working order, but if you come across one that doesn't work, please contact me at WWDD. This page was originally found on another website, which has subsequently been handed over to me. The content found on this site was not written by me, but I have edited some of the original content (i.e. updated links, etc.) as appropriate. My special thanks goes to Bob Patterson, the original author of this page, who graciously allowed me to use his content.


The core information for this page is taken from the website of McGraw-Hill Access Science. The original text can be found there, and further information can be accessed through a subscription to the site. This information will be complimented by my use of "The Five Kingdoms: An illustrated Guide to the Phyla of Life on Earth" by Lynn Margulis and Karlene V. Schwartz. For convenience the taxonomic list is distributed among several separate pages. This information will also be correlated to that which can be found on Tree of Life. The groups on this page will be color coded based on their taxon level, although not all of them will always be used. Those taxa listed in bold font are the commonly known taxon levels. Listed below are the 30 taxon levels used by such sites as the National Center for Biotechnology Information (NCBI) TaxBrowser. They are listed as follows:
