So the Bronx Zoo seems to have misplaced a pesky little thing we like to call a very deadly, aggressive Egyptian cobra, reports the New York Post. The 20-inch adolescent went missing yesterday, and workers who scoured all the likely places it would hide still haven't found it, reports the New York Daily News. The Zoo's Reptile House will remain closed until they locate it. "We are informing the public out of an abundance of caution," the zoo said in a statement. (More cobra stories.)
