Do british snakes (adders) eat fish from ponds?
Yes they will, they are good swimmers, but grass snakes more commonly eat fish from ponds. adders generally eat small rodents, such as the short-tailed vole. They will also eat lizards, frogs and newts, and have been seen taking young from the nests of ground nesting birds.Adders also feed on mice, toads, and insect larvae. The Adder injects its prey with venom and then follows it, waiting for it to die. Grass snakes feed mainly on frogs and toads, but also eat fish, newts and small rodents. They will occasionally take nestling birds. They swallow their prey head first and usually alive!
