"While seahorses typically have a long snout, the snouts of Bargibant’s pygmy seahorses are short and stout—exactly like the polyps on the gorgonian corals that host them. And the seahorses have polyp-like knobs elsewhere on their bodies, too."

#2: Clownfish, & especially how they literally cuddle up with their mint hammer coral fills my heart with joy. How my black male Cousteau begs for food & how Moby constantly photobombs when I'm trying to take pictures of other tank residents. They're so cute!❤️🪸
Moby says HOW DARE YOU try to photograph Acanastrea lordhowensis corals instead of me! (Moby the classic orange clownfish hovers above some yellow and blue coral polyps.) Clownfish Moby (orange) and Cousteau (black) hover above a coral with turquoise tipped purple tentacles. Moby the clownfish hangs out with her hammer coral Moby and Cousteau hang out with their hammer coral even when its tentacles are retracted!

My duncan coral looks slightly grumpy here (how dare I add more calcium to the water,) but it's official: it's working on growing two new heads! 😊 This is a rare victory for me; I've only really had one other coral (apart from my GSP & xenia,) my purple palythoa, produce new polyps so far. 🪸

Honest Q. Should I leave up all my tweets so Grok doesn't screw up coral species ID? 🤷🪸

Here's our crew of baby corals that met Princess Beatrix of the Netherlands in 2021... and I guess also now Chatbotgrok?
16 ceramic tiles on a black plastic rack, each hosting a baby coral one two three years old. Various corals are yellow with long tentacles, yellow and encrusting, brown with tiny round polyps, brownish orange and starting to ruffle into brain shapes, and brown with big fart round polyps and white mouths.

Behold a groovy brain coral! This species, Diploria labrynthiformis, has been having a hard time surviving across the Caribbean. We hope we can continue to help grow little babies to help repopulate the reefs. #MarineLife #CoralScience 🪸
Small round mound of a coral living on top of a rock. The polyps grow in maze-like ridges, making the coral look like a brain. It is not pink though, just a soft light yellow brown. The deep ridges and contours create dramatic shadows and makes the coral look like it’s popping out of the sea blue background. Its common name is grooved brain coral.
