Jacob Colvin on Instagram: "The gumboot chiton (*Cryptochiton stelleri*), the world’s largest chiton species, is often called the “wandering meatloaf” due to its large, reddish-brown, slug-like appearance. Found along the Pacific coastline, it has a leathery mantle that hides its shell plates and iron-coated radula teeth strong enough to scrape algae off rocks. Its teeth also contain magnetite, which may help it navigate using Earth’s magnetic fields. #animals #nature"
