SEQUOIA NATIONAL PARK, Calif. – Twenty-seven previously unknown species of spiders, centipedes, scorpion-like creatures and other animals have been discovered in the dark, damp caves beneath two national parks in the Sierra Nevada, biologists say.

  1. I read this elsewhere and got beaten to the punch on posting it:) This is awesome for zoology geeks, particularly invertebrate zoology geeks. I read all of the progress reports posted at another link. I’ll start a follow up thread since I can’t seem to post links in a comment. Cool stuff and neat pictures. It’s definitely not gonna be for everyone though. Does anyone know what a “harvestman” is and where we see them in Wisconsin? Probably no one knows but the answer may surprise you!

  2. Good guess but…no:) Harvestmen are a group of arachnids that include what we in Wisconsin call Daddy-Longlegs. Yep, that’s right they’re not spiders! Why you may ask?! Well spiders, by definition, have two body segments, a head and an abdomen. Daddy-Longlegs, if you look closely at them, have just one body segment. They are closely related to spiders but have their own taxonomic group. Sorry my geekdom is hanging out again:)

  3. They are new speicies in that they are not previously documented. The question of whether they are recently evolved species or those that have been there for millions of years will be difficult to answer.

  4. A study of the DNA may give some of the answers to how recently they evolved and how closely related they are to others in their genus. PS, I knew that a “harvestman” is in the same group as “daddy-longlegs.
