Caption: Photographed in 1964, on the Caribbean island of Puerto Rico, this image depicted a view inside a snail hatchery stock pond, in which Marisa spp. snails were being raised. These snails would later be released into the wild, in order to prey on the populations of Australorbis spp., also known as Biomphalaria spp. snails, which are hosts to the parasitic worm, Schistosoma mansoni, the cause of human schistosomiasis. In this view, one of the snails was climbing one of the cement walls of the pond, and had stopped when it reached the waterline. The image was captured during a Puerto Rican public health schistosomiasis survey.
