means A large freshwater crocodile native to Africa, one of the biggest and most dangerous crocodilian species, known for ambushing prey at the water's edge.

from The 'Nile' half just names the river system it haunts, famous since antiquity along that waterway and across African lakes and rivers beyond it. 'Crocodile' traces back through Latin crocodilus to Greek krokodeilos, literally 'pebble-worm' or 'lizard of the pebbles' — ancient Greeks reportedly applied the word to the lizards they saw sunning on stony riverbanks, and the name simply stuck to the much larger reptile sharing the shore. The species name niloticus in its scientific label, Crocodylus niloticus, likewise just pins it to the Nile as the best-known home address, even though its actual range sprawls far wider.
