Simon says: "Meet the invasive nomad jellyfish (Rhopilema nomadica)" - summer's sting & sea's strange beauty!
Nomad jellyfish (Rhopilema nomadica) Come summer, Israel's Mediterranean coast becomes a hotspot for these drifters. Love them or avoid them, they're fascinating. 🌿 HABITAT The most infamous is the Nomad jellyfish (Rhopilema nomadica) - an invasive species from the Indian & Pacific Oceans. It entered the Mediterranean via the Suez Canal & has thrived here since the 1970s. Its body is light blue, with a rounded bell commonly 40–60cm in diameter, but it can reach up to 90cm & weigh 10kg! You'll also spot the Fried Egg Jellyfish (Cotylorhiza tuberculata) – harmless & beautiful - plus moon jellyfish (Aurelia aurita) . 🥚 BREEDING Jellyfish have a 2-stage life cycle. Adults release sperm & eggs into the water. Fertilised eggs grow into larvae that settle on the seabed, becoming polyps. These polyps then bud off tiny baby jellyfish (ephyrae) when water temperatures drop. In Israel, we are already seeing massive swarms which will be here through September. 🍽️...
