Some of the weirdest clams to have ever lived: Shikamaia, extinct giant bivalves over a meter long, shaped like a cross between a surfboard and a giant slipper. They lived during the Permian, over 260 million years ago. It has been hypothesized that they rafted on the bottom of shallow, stagnant lagoons, partnering with photosynthetic algae to harvest sunlight for food, like living solar panels. #clamFacts
