Tardigrada

Paper Summary:

Tardigrada, also known as water bears for their appearance, are one of nature's most interesting animals and comprise one of the earth's most diverse phyla. The paper shows that as they continue to be discovered in diverse habitats around the globe, they continue to amaze scientists with their evolutionary adaptations. The paper explores the physicalities of phylum tardigrada including their digestive and sexual reproduction systems.

From the Paper:

"The 800 or more species of tardigrades are difficult to decisively place in one area on the tree of life. However, recently it has been decided that tardigrades belong to a large group of molting animals which includes Drosophilae and C. Elegans. They have been included in many different branches along the tree of life such as Infusoroa, Annelida and Arthropoda. Tardigrada was first identified as a phylum by G. Ramazzotti in 1962. Recent studies have set a new proposal that contains the molting animals including: arthropods, tardigrades, onychophorans, nematodes, nematomorphs, kilnorhunchs and priapulids. In this analysis the morphological similarities are used to relate tardigrades."
