Entering the remote habitats of the saltwater crocodile, the first and most important fact to know is that they will observe an (human) intruder very often, while on the contrary, it would be rare to see them.
Such observations are easy for this extremely attentive animal, as it can be done from a distance while swimming out in the ocean, or inconspicuous lurking under a shady tree, due to an extremely sensitive vision, which helps it to see even in the darkest of nights.
A human intruder will not be seen as potential prey immediately, but as something unpredictable. With an arrival at a place where people are an unusual event, a human has already disturbed hundreds and thousands of animals that he or she has not even seen, the largest and most powerful of which is the crocodile. This behaviour is probably very similar to how you would act if you found someone walking around your house. We would react in exactly the same way as the crocodile by trying to find out what is going on, while cautiously standing out of view behind the curtain.
The left picture shows the head of an observing crocodile in the middle in the shadow of the tree. (Enlarged pictured below). Even for somebody whose eyes are trained to find crocodiles lurking in the water between branches, more often than not the crocodile will remain completely unnoticed.
Somebody without experience recognising them in the wild would be unlikely to see a single crocodile even after having been observed by the reptile for weeks.
The body of the crocodile has evolved to remain unnoticed by potential prey and natural enemies. The shape of the nose and eyes and the colour of the skin are a perfected camouflage in their natural environment and with this in mind, there is no logical reason to believe their behavioural patterns have not reached perfection as well.
Therefore as a human intruder in the territories of this ancient creature one should accept that there is a landlord present that will not be seen if it doesnâ€™t want to be. Due to the inconspicuousness of its behaviour, the saltwater crocodile in its natural environments is widely unknown, even by specialised scientists.
Anyway, latest scientifically evidence suggests that this animal is very smart and that it has been previously underrated in its intelligence >
