There is no such thing (in English) as a "mammle." There is, of course, a mammal. The deadliest mammal is arguably the hippopotamus, not the African lion, not the Bengal tiger, not the orka ("killer whale.") You may get an argument about that from a seal or a gnu, but the published opinion of experts in the field is that the hippo is the most dangerous.
