Siphonaria compressa

Siphonaria compressa is a species of small, air-breathing sea snail. It is a pulmonate limpet, a gastropod in the Siphonariidae family. It is endemic to South Africa. A further site for this false limpet was discovered in 2004 in the Knysna River estuary (S34 03:E23 03) South Africa by Dr B. R. Allanson (the original describer of the species). The length of the shell is 4-4.5 mm. It is the smallest species of Siphonariidae. This small false limpet lives on the leaves of the marine plant, eelgrass.
