Females can weigh about 40 kg (88 lb). Freshwater crocodiles are very shy animals. Along with a slender snout, their teeth are smaller than the dangerous saltwater crocodile.

  4. ... johnstoni means "of Johnstone", derived from the name of the first European to discover and report it to Krefft. Unfortunately Krefft misspelled the name "johnsoni " in his initial description and his subsequent correction was ignored until 1983 when the nomenclature was reviewed thoroughly by Hal Cogger (Cogger 1983). Although the majority of scientific literature, including all Australian Federal, State and Territory legislation has been using "johnstoni " correctly since then, the uncorrected version is still popular especially in the US on the basis of a later taxonomic review (King and Burke 1989) that ignored Cogger's revision.
