Otter filmed underwater
A submersible camera captures an otter...
Otters are elusive and there will be a large number of 'empty' videos to play through before finding an otter (if at all). However the odds can be increased if you film at dawn and dusk. Underwater CCTV cameras are not suitable for use at night in fast flowing rivers (such as the River Bovey) as passing debris reflects the infrared light from the camera and obscures the image.
