Scientists are reporting an invasion of hungry American bullfrogs along the Yellowstone River in the US state of Montana. The bullfrogs are said to eat nearly anything, including other bullfrogs, and pose a threat to native species. The number of the animal's breeding sites has nearly quadrupled since 2010.
