🐚🦀 It's National Hermit Crab Day! Land hermit crabs—like the ones often sold in stores by the seashore—can live to be 40 years old and grow to the size of a coconut. 🥥 At the Zoo’s Think Tank exhibit, these charming crustaceans teach visitors about animal intelligence and tool use. Go behind the scenes with primate keeper Erin Stromberg and intern Noah Goldfarb for an in-depth look at how they care for our crabs. ✏️STORY: s.si.edu/3FeN0zt. | Smithsonian’s National Zoo and Conservation Biology
