Shrimp and Goby
Goby/Shrimp
the shrimps dig and dig and dig and they're blind and the gobys are very visual creatures - but have no real defense mechanism, so they rely on the shrimp for shelter the shrimps use their antenna to stay in "touch" (litearlly) with the goby and if the goby sees danger, he'll shiver and the shrimp will run back into the hole and if the shrimp goes and getsfood... and gets lost.. the goby will see him and run over and touch his antenna...and lead him back to his hole
if they're unable to dig or have different type of (blah) to burrow out... lower chance of survival they've evolved into diggers

The shrimp and the goby have an essential partnership. While the shrimp build and maintain a burrow for both to live in, the goby sits in the entrance keeping guard and warning the shrimp, which is nearly blind, of all surrounding danger. There is a benefit to both even though the shrimp does most of the work. The goby uses the shrimp’s burrow for protection from predators, and he acts as the “eyes” of the shrimp. Once the shrimp initiates building, he keeps an antenna on the tail of the goby, even if he deviates from the cave, the can always come back. When the shrimp goes too far, the goby will help him find his way back. When a predator approaches, the goby flicks his tail several times, and they both retrieve into the burrow.
1) If the shrimp is unable to perform the mechanisms to dig and maintain its burrow, then the shrimp has a lower chance of survival.
a. Prediction: We can predict, by removing his claws, the shrimp is not able dig and maintain his burrow.
2) The shrimp has evolved antennas and adapt them to the purpose of communication. If the shrimp is unable to communicate with his antenna, then he is unable to benefit from mutualism.
a. Prediction: We
