Opabinia drifts past with all five stalked eyes open and its long grabby trunk curled mid-reach, painted in vintage natural-history colour: rust-striped back, teal swimming lobes, and glossy black eyes on a chocolate tee. This little Cambrian oddball swam over 500 million years ago, measured only a few centimetres long, and used the claw at the end of that trunk to pass food to a mouth that faced backwards. Evolution was just showing off. Made from lightweight 100% ring-spun cotton with a soft, sensory-friendly feel. Every order funds kelp restoration on the Pacific Northwest coast.
