Giant crab spiders of the genus Olios are distributed in the same rain forest microhabitats as preadult Eleutherodactylus coqui . The ability of these spiders to capture E. coqui of different sizes was investigated by offering frogs, suspended by threads to crab spiders in the field. Results indicate that survival of frogs is dependent on their size and that larger frogs survive encounters with spiders more often than smaller frogs because the larger individuals are able to escape after capture by kicking free of the spiders.
