Shown here are two grass puffers (Takifugu niphobles), a small species of pufferfish native to the northwest Pacific, riding a wave onto shore for the purpose of group spawning. 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. This is the only puffer species known to do this.
