“…Today we’re talking about a small fry with a loud personality and the fastest draw this side of the Mississippi… and the other side too. But more on that later…
You don’t really think of the ocean being a noisy place, but it can get pretty rambunctious down there sometimes. One of the chief troublemakers and loudmin extrordinaire is the Pistol Shrimp. He’s great at parties, but he makes for a bad tenant. With a snap that would put the Mad Titan to shame, this high-decibel decapod can stun and even kill its prey. Life may be hard for most, but hunting and surviving are just a snap for the pistol shrimp here in Life, Death, and Taxonomy.

Since we learned about mutualism last week, we now come across another animal that shows mutualistic behavior, this time with another animal.
- The pistol shrimp often shares a burrow with the goby fish.
- The shrimp builds the burrow and maintains it.
- The goby has good eyesight and alerts the shrimp to danger.
- Even when they leave the burrow, they shrimp will keep track of the fish with its antennae.
- If the fish spots danger, it will communicate with the shimp with a special tail flick.
- One genus (Synalpheus) displays eusocial behavior like the naked mole rat.
- Colonies live inside sponges with 300 members.
- All of them are the offspring of a single large female queen, but they may also be offspring of one male as well.
- The colony is separated into workers and soldiers.
- Workers tend to young and soldiers protect the colony.
