Lesser Octopus filmed at Worms Head, Rhossili, Gower

John Wills, an undergraduate student in the Department of Biosciences, College of Science, Swansea University, caught this fascinating creature on camera.

The footage was taken on the causeway to Worm's Head, Gower and is thought to be a Lesser Octopus (Eledone cirrhosa).

John estimated its size to be approximately 30-40 centimetres from tentacle tip to the end of its body. John watched as it moved out from under a stone to the edge of the pool where it used its propulsion system to squirt water accurately in our direction. "I didn't expect this 'aggressive' behaviour, but in retrospect the animal was cornered and our presence obviously stressed it. We immediately moved away after this video was taken so as not to distress the animal further". The animal seemed healthy and the rock pool was deep and large enough to sustain it until the next tide.

If you watch closely, the film shows the octopus changes colour very rapidly.
