The long structures seen in manta rays and their relatives function as an early warning system, rather than a defensive weapon.<\/p>\n

With hornlike facial fins and diamond-shape bodies that can stretch nearly 30 feet across, manta rays are among the strangest fish in the sea. Yet these behemoths\u2019 most puzzling feature is a whip-like tail that can measure as long as the rest of the fish\u2019s body.<\/p>\n

Why mantas and related rays have such long tails has long been a mystery. The fish do not use their tails to propel through the water or to lash out at potential predators. And although stingray tails have a fearsome reputation<\/a> for deadly stings, manta tails lack defensive spines entirely.<\/p>\n

Instead, these elongated tails may act as fine-tuned antennae, specialized to detect approaching danger. In a paper published on Wednesday in the Proceedings of the Royal Society B: Biological Sciences<\/a>, a pair of researchers analyzed tails belonging to cownose rays, a smaller relative of manta rays. They discovered that this elongated structure contained specialized organs that help sense underwater stimuli, hinting at how other oceanic rays may use their rear appendages.<\/p>\n

\u201cThe complexity inside the tail was super surprising,\u201d said J\u00falia Chaumel, a marine biologist at Harvard University and an author of the paper. \u201cWe had no idea that this huge structure had a sensorial function.\u201d<\/p>\n<\/div>\n<\/div>\n

While most stingray species reside near the seafloor, mantas and other rays in the myliobatid order spend most of their time in open water. These fish flap their enlarged, triangle-shaped pectoral fins to fly through the water and migrate over long distances.<\/p>\n

According to Matt Ajemian, a researcher at Florida Atlantic University who studies sharks and rays, most stingrays have short, muscular tails that they use to flex venomous barbs. But myliobatid rays possess very different backsides.<\/p>\n
