Seals use acoustic tags to hunt more efficiently
Howard Hall commented here on Wetpixel about the proliferation of tags that are festooning some marine animals and the potential negative effects that these may have on the animals that the studiers seek to understand. A paper published recently in the Proceedings of the Royal Society B entitled Grey Seals use anthropogenic signals from acoustic tags to locate fish shows how grey seals (Halichoerus grypus) have learnt to use the signals emitted by fish tags as an aid to hunting more efficiently.

Howard Hall: Tagging - a celebration of science?
Filmmaker Howard Hall explores the issues around the tagging of marine creatures for scientific research. Whilst the technology and data that tagging programs can provide is amazing, are the studies in the animals or the researchers best interests? Is the proliferation on tagging programs really giving us the scientific data we need to protect the creatures, or are we damaging the very animals we seek to protect with them?
