Freshwater Life

Malcolm Greenhalgh studied freshwater ecology and received his PhD in estuary ecology. As a freelance researcher and writer, he has appeared on television and the radio and has taught groups of naturalists and fly-fishers throughout northern Europe how to identify aquatic plants and animals. He has also carried out investigations into the plant and animal life of rivers and lakes for wildlife organisations and riparian owners and has published various papers, articles and books on the subject.

‘Denys Ovenden captures so much detail and beauty in his drawings of insects such as the caddisflies, mayflies and stoneflies. His treatment of the water fleas would justly grace the wall of an art gallery.’British Wildlife‘Refreshing originality … the unusual format works exceptionally well and beautifully depicts aquatic life from the unicellular paramecium to small fish and frogs.’Mark Cocker, The Guardian
