[Music] recently in Bermuda something believed extremely unlikely happened a tagged and Pregnant poor beagle shark was eaten by another shark researchers who were tracking its movement noticed its satellite tag was exhibiting some really strange Behavior with marine biologist Brooke Anderson saying about it I kept trying to think of alternative explanations for the increase in temperature depth but all signs pointed to the same conclusion that our pregnant female porbeagle had to have been eaten by any even larger shark poor beagles aren't easy prey either as they grow to be upwards of around 12 ft long and weigh around 500 lb however their numbers are dwindling due to Sport and Commercial Fishing meaning if other large sharks are now eating them this could be very bad news what's even worse is that while they live for decades they don't begin to reproduce until around 13 years of age they also only have a litter of up to four pups just every year or two meaning their reproductive cycle is quite slow so what kind of shark made a mature 12T long por beagle it's dinner the researchers say because of the increased temperature it was likely a great white shark or a short fin moo as both generate heat inside their bodies [Music]
