Seeing Eye Fish
There's an old saying that people seldom remember how rapidly the job was done, but they do appreciate good workmanship. However, the staggering variety and number of things created by God did not limit the elegance of His fine workmanship.
The relationship between the snapping shrimp and a fish called the goby is a good example of the Creator's attention to the finest detail. The snapping shrimp has very poor eyesight, while the goby has excellent eyesight. Both share the same burrow, which is dug by the shrimp and guarded by the goby.
The shrimp uses the goby as a blind person uses a Seeing Eye dog. Whenever the shrimp is outside its burrow, it always keeps one antenna on the goby. The shrimp stays hidden inside the burrow if the goby should temporarily swim away. When danger approaches, the goby signals and disappears inside the burrow. The shrimp is right behind him.
Neither the goby nor the shrimp can survive without each other, so pairs are established for life when both goby and shrimp are very young. In order for this system to work, both goby and shrimp reproductive systems, which differ greatly, are synchronized so that shrimp and goby youngsters are ready to pair at the same time.
This astonishing relationship shows us how our Creator's standards of excellence bring His love to every corner of the creation.
