Super cute, right?

This interesting pair live together. The Yasha Goby - Stonogobiops yasha - guards and signals the Candy Stripe Pistol Shrimp - Alpheus randalli - when it is safe and when it is time to duck for cover. The shrimp always keeps at least one antennae on the fish, and when it feels a sudden twitch it knows to retreat into its hole in the sand.
