Many sources say that coral polyps hide down in little holes. That couldn't be more wrong. Polyps are so soft-bodied it's hard to imagine. Their skeleton is formed underneath them, like people have bones inside them. And coral skeletons are sharp as razors. The lightest human touch pushes coral's flesh into their skeleton, causing much harm.
Polyps grow from one single baby polyp that, once old enough, "buds" little polyps on their edge. Sort of like how one little bit of grass spreads. They are always connected like a rug, and they share food and bodily fluids. This 'rug' of polyps lives covering the hard white part of the coral that you find for sale in some stores, ugh. Skeletons as ornaments?
Here are the same polyps, ten weeks later. They're making babies, clones if you will. And some have their tentacles extended, waiting to catch passing food. The bare skeletons have been overgrown by algae.
The polyps are a little pale because the sea was too warm when the photo was taken.
Thanks for stopping by, time to go for a dive and see what I can find...

These fish, Black Durgons, have a striking white line at the base of their dorsal fin. The way they swim, going through the water looking for bits of floating things to eat, they undulate their dorsal and anal (top and bottom) fins to move through the sea. As they slowly swim, they lean over on one side, and then the other. Dancers, they are. They usually stay up in the water column, high over the reef. But I guess on this day, here is where they found their prey, tiny jellyfish? I don't know what they eat.
At night, they sleep down in crevasses and cubbyholes in the reef.
I'll get back to painting soon. Thank you for stopping by.
