Cuttlefish can change colors to instantly blend in, a lot of animals have color patterns to disappear into their typical surroundings, but did you know that some spiders can change color too? This week we talk about the goldenrod crab spider, whose camouflage abilities help them to disappear on meadow flowers so they can nab their prey and hide from predators. Tune in to hear about the color-changing abilities of the goldenrod crab spider and the surprising ways they use prey pigments along with their own pigments to change colors!
