The first and third prize in the GNHS Photography Competition 2011 went to these amphibian themed photos taken during my field work:
This photo actually shows a water mould (Saprolegnia sp) attacking and killing common frog eggs. The photo was taken looking down a microscope. Saprolegnia initially attacks dead eggs within a clump, but spreads rapidly to live eggs. It can cause widespread mortality within a pond and is of economic importance to fisheries as it also infects fish eggs.
