Anthomeduseae, also known as hydrozoans, are a fascinating group of marine organisms that inhabit various aquatic environments around the world. From the vibrant Red Sea coral reefs to garden ponds in Derbyshire, UK, these creatures can be found in diverse ecosystems. One example is the Blue dragon seaslug (Glaucus atlanticus) with its striking appearance and unique feeding habits. It often preys on the Blue button hydroid colony (Porpita porpita), forming an intriguing predator-prey relationship beneath the ocean's surface. In garden ponds of Derbyshire, UK, another member thrives - the Green hydra (Hydra viridissima). Its presence adds a touch of natural beauty to these man-made habitats and showcases nature's ability to adapt and survive even in unexpected places. Moving back to the mesmerizing Red Sea coral reef scene, we encounter schools of Scalefin anthias fish (Pseudanthias squamipinnis) gracefully swimming among Fire corals (Millepora dichotoma). These females feed on plankton brought by currents, highlighting their vital role within this delicate ecosystem located in Ras Mohammed National Park, Sinai, Egypt. The Male Emperor angelfish (Pomacanthus imperator) takes center stage as it glides over a stunning garden of Fire corals (Millepora sp. ) illuminated by morning sunshine. This majestic sight can be witnessed at Ras Mohammed National Park too – truly a paradise for underwater enthusiasts. Emperor angelfish continue to captivate our attention as they swim alongside soft corals such as Dendronephthya sp. And Scleronephthya sp. , accompanied by Scalefin anthias. The harmonious coexistence between these species exemplifies nature's intricate web of life found within coral reefs worldwide. Venturing into Guanaja Island in Honduras' Caribbean Sea, we encounter Blade fire coral (Millepora complanata) colonies.
