Multilegged mayhem

After painstaking research, at least one culprit has been identified behind some of the deformities recently seen in frogs in the us . Trematode rather than pesticides are responsible for some of the deformities seen recently in frogs by scientists at the Hartwick College in the us. The minute trematodes, called Ribeiroia , burrow into the hind limb buds of tadpoles, wreaking havoc with leg growth. However, the crippled frogs may help their parasitic cargo infect its primary hosts.
