Anything is possible when you work together!! These guys hang out together constantly. The pistol shrimp has formidable claws but is nearly blind. The pistol shrimp has an enlarged claw that functions much like a gun, and is capable of firing compressed bubbles that help it stun and catch prey, or scare away predators. The watchman goby has fantastic eyesight, but does not have much of a defense. The pistol shrimp builds tunnels under the sand that these guys share. These guys really depend on each other for survival. They are fun to watch.
