Opabinia Sook T-Shirt

Celebrate one of prehistory’s weirdest wonders with the Opabinia SOOK T-Shirt. Featuring a beautifully detailed vintage-style illustration of the iconic five-eyed Cambrian creature, this design leans into science humor with a single bold word: SOOK. A clever nod to how this ancient marine animal likely fed—using its unique proboscis to grasp rather than “suck.” Rendered in a classic sepia tone for a natural history museum feel, this shirt is perfect for paleontology fans, fossil enthusiasts, evolutionary biology nerds, and lovers of wonderfully strange ancient life. Subtle, smart, and delightfully niche, it’s a guaranteed conversation starter. Made from 100% ring-spun cotton (high-quality cotton) with a soft, sensory-friendly feel. Every order funds kelp restoration on the Pacific Northwest coast.
