Molting Secrets, Mantis Shrimp Vision and the Boxer Crab s Anemone Gloves

Crabs in disguise, shrimps with super-vision, and a molt captured start to finish. The ocean’s “insects” are stranger than fiction.

Dive into the hidden lives of crustaceans, from the Japanese giant spider crab’s vast reach to a rare, full molting sequence filmed in a controlled night setting. Meet the mantis shrimp with extraordinary 3D eyesight, watch boxer crabs brandish living anemone gloves, and see how hermit crabs risk everything to swap shells. Discover cleaner shrimp “stations,” the surprising alliance of a blind shrimp and a watchful goby, and barnacles that filter-feed where sea meets air. Then trace survival tactics that border on art: spider crabs grafting camo, skeleton shrimps spinning sticky nets, and brine shrimp eggs built to endure extreme cold and heat.

From predators to parasites and from micro to colossal, this episode reveals behaviors you’ll only believe when you see them. Watch to uncover how these animals grow, hunt, hide, and outwit danger in ways that rewrite what you think life underwater looks like.

Watch now and see the ocean’s most inventive survivors up close.
