What do a blind cave spider, a volunteer surrounded by one hundred hungry mosquitoes, and thousands of crabs piling on top of each other all have in common? They all made today's episode.

Nathan takes you from the caves of Mexico to the seafloor of Australia and back again, covering some of the most surprising and strange stories from the world of arthropods and insects this week. There is new research that will make you rethink everything you assumed about tarantula intelligence, a pollution story with consequences far bigger than most people realize, and an invasive species detection in Hawaii that has experts watching very closely.

Whether you are a lifelong invertebrate enthusiast or just someone who appreciates the weird and wonderful side of the natural world, this episode has something that will stick with you.

Come for the science. Stay for the spider crabs.
