Most insects and some arthropods prefer bushland. Each of them claims their own territory with certain boundaries that no one may violate. Punishment for those who break it may be prey, or a fight will occur if both are equally strong.
But there are also those who like open places where they also have their own territory. Being out in the open didn't mean they couldn't hide in the presence of a stronger enemy. That's because their physical characteristics can blend with or adapt to the nature in which they live.
The stone spider is one of them. In arachnology, it has the Latin name Pardosa sumatrana , and this is still in the large family of wolf spiders.
This species is common in rocky rivers. Such a physique allows the stone spider to perform perfect camouflage both on the surface of the water and on the rocks.
In the water? Is the spider not sinking? Of course not; it could even cross from rock to rock by crawling extremely fast over the surface of the water.
