Modern-day otters are pretty charming. They're playful and cute. But you might not

think Siamogale melilutra, an otter that lived 6 million years ago, was cute if you met one. A study led by the University at Buffalo found the large, prehistoric otter was likely a top predator with a shockingly powerful bite. The ancient otters got up to 110 pounds (50 kilograms) in size. North American river otters can get up to around 30 pounds (14 kilograms), though the endangered giant otter found in South America can weigh over twice that. The researchers used fossils to help create 3D computer models of the prehistoric otter's jaws to compare with modern otters. Today, smaller otters have sturdier jaws than larger ones. The wolf-sized prehistoric otter defies this modern trend with researchers saying its jaws "were six times sturdier than expected." "Our findings imply that Siamogale could crush much harder and larger prey than any living otter can," said lead researcher Z. Jack Tseng with the University at Buffalo.                                                                                                                     https://www.cnet.com/news/prehistoric-otter-surprisingly-killer-bite-university-at-buffalo/
