Crown of thorns, Regal angelfish
Here’s another find under the coral. The crown of thorns is largely an ugly scary looking thing. Occasionally it is a very nice subject for photography because it can be quite colorful. This one was deep in a coral crevice. And there was an angelfish lingering around it. That was the picture. This starfish eats and decimates the coral reef in some parts of the world. It’s very hard to kill. But you can kill it with cow bile. Bet you wanted to know that? And how did they discover that?
