Yawunik kootenayi
Yawunik kootenayiYawunik kootenayi patrolled middle Cambrian coastal waters as an agile, dual-purpose predator equipped with specialized frontal limbs. These grasping appendages ended in three robust claws lined with fine teeth alongside elongated, whip-like flagella used to sense both chemical and physical signals in murky waters. Undulating paddle-like limbs along its segmented trunk propelled the animal through the water column, allowing it to ambush smaller invertebrates across the prehistoric sea floor.
