Ramshorn Snail Illustration

ramshorn snail illustrationVintage black and white ramshorn snail illustration from an 1848 book. These air-breathing freshwater snails can grow up to 1.57 inches around. Their shells are coiled to the left. In describing these snails, Jane W. Loudon, said the shells had a horn-like look about their shells reminiscent of a ram’s. They also have an interesting defense mechanism. When threatened, the snail emits a dark reddish liquid. The liquid effectively muddies the water so that the snail is hidden from its enemies. They lay their eggs on leaves. The scientific name of these snails is Planorbis corneus.
