great pics again, dude !

I really enjoy your posts more and more - the variety is extraordinary.
In the 2nd pic you can see that much thinner legs - maybe because this species is specialiced on hunting in trees. and in the 3rd one we can see those much shorter stronger legs - i asume that it lives on the ground.
guess you can see that effect on spiders, too - i'm not a biologist - those are all just speculations of mine.

The second.... A fly.... He or She eat a fly.... This one must be really fast.... Real nice pics....

But i don't know if the legs thinner.... Maybe they only look thinner on the pic....

Very good observation, you are very correct! Neotiwaripotamon whiteheadi is highly adapted to an arboreal lifestyle, it's slender and elongated ambulatory legs help it firmly grasp on to tree trunks. In contrast, the short and stubby legs of the Apotamonautes hainanense are well suited to a digging holes and moving large rocks on the forest floor.

It is eating a termite and yes it is very fast indeed!

The legs of N. whiteheadi are indeed thinner.
