Depicted here is the chaos of spawning of grass puffers (Takifugu niphobles) rushing onto a beach, female in the middle. This species has the unusual habit of spawning on land. At certain times of the year, large numbers in shallow water at high tide. When larger females beach themselves to lay eggs, males follow to fertilize. The fish rely on waves to take them ashore and return them to the ocean. Native to the northwest Pacific, grass puffers are the only pufferfish known to spawn onshore.
