Followed by a Flounder

Hooray! Even though I've started my full-time office job, I was able to get in an ocean swim after work yesterday. Whew!

This little crab on the ocean floor was being followed by a flounder. The crab would take a few steps, then the flounder would move up behind. Over and over. As I continued my swim I looked for more crabs, and found more flounders as well. It seems to be a thing.
