Join us as we explore the vibrant world of Galaxea fascicularis, also known as octopus coral, fluorescence grass coral, or galaxy coral, found thriving in the Red Sea and across the Indo-Pacific. Discover how these colonial creatures build their stunning structures, from small domes to massive 5-metre wide formations, and even learn about their daytime feeding habits where their tentacles hide their stony skeletons. This episode unveils the beauty captured in a photograph off the coast of Egypt.
