RSPB Ham Wall slime may be frog spawn, vet suggests
A Devon vet believes he has unravelled the mystery of slime spotted at a Somerset nature reserve.
Several mounds of a jelly-like substance found at the RSPB's Ham Wall base had baffled wildlife experts.
Vet Peter Green contacted the charity and suggested the four-inch (10cm) mounds were related to frog spawn.
He said the spawn was held in a "glycoprotein", and if attacked the female dropped the spawn and "jelly" surround.
