The Essential Guide to Beachcombing and the Strandline (Wild Nature Press): 4

Steve Trewhella is a diver and photographer specialising in British marine life above and below the waves. He is a keen naturalist and when not diving enjoys beachcombing, rockpooling and recording strandline and coastal invertebrates. His beachcombing finds include new species records for the UK and new information about the distribution of wildlife endemic to strandlines. His images are used in publications all over the world and he has worked as a contributor on many natural history television features.

Julie Hatcher is a marine biologist working in marine conservation in Dorset. Her work involves raising awareness of the marine environment and marine and coastal wildlife in the UK, and she has written many articles for newspapers and magazines, as well as designing interpretation panels, posters and leaflets. She also leads guided rockpool rambles and seashore identification training courses, and has been a scuba diver for many years, mostly in the UK.

Steve and Julie met in 2004 since when they have jointly organised projects to record Pink Sea Fan skeletons, long-haul litter and strandline invertebrates as well as carrying out dive surveys for seahorses and stalked jellyfish. Their combined knowledge and interest in beachcombing has developed over many years, fuelled by inspirational characters along the way. A desire to share their understanding of this fascinating activity has led to this book.
