Male slender-snouted crocodiles are territorial, not tolerating males and only living with females during mating seasons.
Although reliable information regarding specific sizes of home ranges and territories is sparse for crocodilians, all species, including slender-snouted crocodiles, display dominance hierarchies between males.
Male slender-snouted crocodilians are very territorial and will not tolerate other males or intruders in their territories. This often leads to battles between dominant crocodiles and intruders. Males show their dominance to intruders using different rituals, including raising their bodies out of the water to try to appear larger in order to intimidate their intruders.
Males will only live near females during mating seasons, passing from female to female within their territory. Dominant males will breed with all of the females within their territory.
