Sea jelly!

Sea jelly!

Sea jellies, often referred to as jellyfish, are fascinating marine creatures that have roamed the oceans for over 500 million years. These gelatinous animals are composed of 95% water and lack a heart, brain, or lungs. Instead, their movements are governed by the flow of the water they inhabit. Sea jellies belong to the phylum Cnidaria, which includes other marine organisms like corals and sea anemones. They are known for their bell-shaped bodies and trailing tentacles, which can deliver a sting to capture prey.

The diversity of sea jellies is truly remarkable. They range in size from tiny medusae smaller than a pea to the enormous lion’s mane jelly, which can have tentacles extending up to 100 feet. Sea jellies can be found in various colors and patterns, with some species displaying intricate designs on their bells. For instance, the moon jellyfish is known for its translucent bell adorned with delicate, lacy structures, while the flower hat jelly boasts vibrant, flower-like appendages.

Sea jellies play a crucial role in marine ecosystems. They serve as both predators and prey, helping to maintain the balance of marine life. Despite their simple anatomy, sea jellies have adapted to survive in diverse environments, from the deep sea to coastal waters. Their ethereal beauty and otherworldly appearance continue to captivate scientists and ocean enthusiasts alike, making them a popular subject for marine photography and aquarium displays.
