A pod of pilot whales exhibited some strange behaviour whilst in shallow water on the Shetland Islands, UK the other day. A description of the encounter, along with photos and video can be accessed by going to http://www.earthinfocus.com/blog/detail.php?id=13. We'd be interested to hear from anyone else who has seen this kind of behaviour and has an idea of why they do it. Many thanks, George Stoyle Earth In Focus
