Hallucigenia

Hallucigenia is so named because, well, look at it. It doesn't look like a real thing! Until 2015 scientists weren't even sure which end was the top or bottom, or the front or back! Most specimens have a stain that was at many times mistaken for a bulbous head. The actual head has two eyes and a radial jawless mouth, and the throat has pharyngeal teeth. Hallucigenia has seven pairs of legs and seven pairs of spikes on its back (which were previously thought to be stiltlike legs). Related to modern velvet worms, Hallucigenia probably walked around the seafloor eating detritus. Hallucigenia can be found in the Cambrian section of the Aquarium. |
