"The Reptile House was closed yesterday after staff observed that an adolescent Egyptian cobra was missing," New York's Bronx Zoo has informed the public, out of "an abundance of caution." The twenty-inch snake was apparently being held at an off-exhibit enclosure that is not even open to the public, according to Gothamist. "Based on our knowledge of the natural history and behavior of snakes, we know they seek closed-in spaces and are not comfortable in open areas. We are confident that the snake is contained in a non-public, isolation area within the building," the zoo said in a statement. Phew. So don't even think about the fact that, according to CNN, the Egyptian cobra's venom is "so deadly that it can kill a full-grown elephant in three hours." Everything's fine.
