Anyone interested in zoology should check this out. It is a blog post on sea spiders, a strange and rare group of invertebrates. Recent research suggests that they may be relatives of some of the more bizarre Cambrian arthropods. Pretty wild! In my invert zoo class at UNL, we got a shipment of marine animals from the Pacific Ocean. For about 3o seconds we thought we had found a sea spider...our excitement subsided when we realized it was just a normal spider that had drowned in the salt water.
