steve-o, i actually recently learned the reason for their high legs. its very cool
i also found out that, while normal spiders (who often live on surfaces, walls, etc) will flee a long way, and hide well, if scared
the daddy-long leg (who lives in brush and grass) will only flee a few centimetres, probably since in nature, that would be far enough. theyll be well hidden by the grass, where a normal spider is used to having to flee further, and hide better.
i love experimenting
