A beautiful animal but a deadly hunter. The common cuttlefish, Sepia officinalis, has an amazing ability to rapidly change its colour - so rapid in fact that waves of different colours sometimes seem to flow across its body. It catches its prey - small fish, crustaceans and so forth - by stealth, slowly stalking them and then shooting out two very long tentacles which have broad, flattened ends covered in suckers. More often seen in the south and west of the UK.
