Consider culture. Some dolphin populations demonstrate learned behaviors transmitted across generations: signature whistles that operate like names, foraging techniques that depend on local features (such as mud-ring feeding), and even tool use—some bottlenose dolphins carry sponges on their rostra to protect them while probing the seafloor. These are not isolated curiosities but the outlines of a distributed knowledge system. Zek, as a motif, points to the accumulation of small, local inventions that confer advantage and meaning to a group. It invites us to treat dolphin societies as repositories of knowledge, not merely as collections of individuals.
