Extract

The freshwater medusa, Craspedacusta, has been taken again in its classic semi-natural locality, the Exeter Canal. While tow-netting for freshwater plankton on 15 September 1976, in connexion with a study of the food of endemic fish populations, one male specimen of the olindiadid limnomedusan Craspedacusta sowerbyi Lankester (1880) was found. The locality was 300 m on the Exeter side of the Turf Lock (map reference SX 963863) and the net, mesh size 50 mpi, was being towed from a small rowing boat at a depth of approximately 1 m at noon in weather of occasional sunshine, the water temperature being 20 °C.
