In some mangrove wetlands along the coast of eastern India, a mugger crocodile (Crocodylus palustris) must defend its kill from a larger saltwater crocodile (Crocodylus porosus)!
(I don’t actually know for sure if mugger crocodiles are capable of bringing down Bengal tigers like the one in my picture did, but it seems likely to me that larger muggers would be able to if they catch the tiger swimming through water.)
