Stumbled upon the site Catalogue of Organisms for those with an inordinate fondness for systematics. It’s high on the geek-o-meter which is probably why I love it so much. You got to love a site that dedicates a whole post to Gastrotrichs. Christopher as done a couple posts on deep-sea fish, the personal favorite Gonostomatidae* and the Saccopharyngiformes.
