Coral Patches

I found this very cool article about coral patches over at TreeHugger. It basically explains how scientists are able to use satellite imaging to directly view a particular marine behaviour, called coral patches. It’s basically when a herbivore/bottom feeder will always leave a small patch of seaweed to swim back to for refuge and they will slowly eat around their homes creating these circular patterns.

One thing I found interesting about this article is how it explains that in coral reef ecosystems, there is a much greater number of predators competing for a limited supply of prey, sort of like an inverted pyramid. That is sort of the opposite of most ecosystems on land but it is apparently incredibly healthy for the coral reefs, lest all the herbivore prey eat too much of the aquatic flora.
