So far, it seems to be a brazilian poisonous "aranha ponte matadouro". The way in which its feet are position and its colors seem to be those of a "ponte matadouro". However, I will keep searching just in case and ID suggestions, critiques or comments are always welcomed =) So far, I couldn´t find its scientific name either.
While walking near an open area in the middle of "Navegantes" town, the colorful spider hanging between two branches called my attention. Its head and abdomen were about three centimetres long. It looked like a lovely nature portrait just hanging there in the middle of nowhere; and probably some of the dragonflies flying nearby must have fallen in its trap...although the spider probably moved to one side; or not?
