Can anybody tell me what this is please? Came on a rock from the gulf. Used to be really tiny but now it is the size of a quarter. It is kind of wiggly
Could be a baby fungia. If so eventually it will fall off that spot and go to the sand. And it will generate another in its place. Good find, nice hitch hiker. Here is a picture of a very productive site.
looks like a plate coral that reproduced several times. Or.... a Cactus coral (Pavona). As they mature, they sprout shoots. I have one of these on a rock of mine, really cool.
