Juvenile Amblypygid, aka tailless whip scorpion. These arachnids look intimidating, but are completely harmless unless you're a moth or a cricket (Heterophrynus elaphus, Peruvian Amazon).

Adult Amblypygid (Heterophrynus elaphus). Note the small cluster of moth wing scales on its raptorial pedipalps, near the lower right - perhaps a moth was its last meal. (Peruvian Amazon)

We watched this wandering spider grab this moth literally out of mid-air. The moth flew past, attracted by our flashlights, while one of us was setting up to photograph the spider (Peruvian Amazon).
