Crocodiles have just one olfactory chamber as well as vomeronasal organ is absent in the adults[77] indicating all olfactory perception is restricted to the olfactory process. Behavioural and olfactometer experiments indicate that crocodiles detect each air-borne and drinking water-soluble chemical compounds and use their olfactory process for looking.
The upper surfaces of the back and tail are covered with significant, rectangular attractive plates organized frequently in longitudinal and transverse rows. The majority of the dorsal plates have a longitudinal ridge, or keel.
