Ever wondered what baby corals look like? Check it out! 🔬
Here we have grooved brain coral babies (𝘋𝘪𝘱𝘭𝘰𝘳𝘪𝘢 𝘭𝘢𝘣𝘺𝘳𝘪𝘯𝘵𝘩𝘪𝘧𝘰𝘳𝘮𝘪𝘴)! These corals were given to us as larvae from (thanks guys!) about three months ago, and we are happy to say that we have almost 200 recruits!
Coral larvae are free-swimming until they find a place on the reef they’d like to live. They ‘settle’, and start growing into polyps! In these pictures you can see multiple coral polyps that have settled so close to each other they look like they’re growing into each other. This is actually a phenomena that we may see play out in real time called Chimerism. This is where two or more genetic individuals fuse together early in settlement. Coral chimeras can show enhanced resilience and increased growth rates!
