So next time you hear about mysterious objects splitting apart in the deep, this ocean creature collective might be behind that ocean mystery. | OceanX

This might be the longest creature ever spotted in the ocean! 🌊😮 Scientists spotted a swirling siphonophore off the coast of 🇦🇺 Western Australia. Estimated at 150 feet long, “It looked like an incredible U.F.O.,” said Dr. Wilson, a senior research scientist at the Western Australian Museum. The siphonophore, which is related to jellyfish and corals, looks like a long gelatinous string and is formed by thousands of small, specialized cells (called zooids) that work together to create a funct

Siphonophore anatomy 101: This siphonophore, Bargmannia lata, has a “head” (nectophore) made of swimming bells and a “stem” (siphosome) that contains parts for feeding, defense, and reproduction.⁠⠀ ⁠⠀ Siphonophores range from 10 millimeters to 30 meters (less than half an inch to almost 100 feet)—longer than a blue whale! They are important midwater predators, deploying long curtains of stinging tentacles to prey upon various crustaceans and fish. These gelatinous animals are extremely fragile a
