A wildlife enthusiast has captured the moment a seal dives below the sea and emerges with a fish in its mouth, which it then devours.

Keith Ross, who makes short wildlife clips and posts them to his Twitter page, took this amazing video just off the Ramsgate coastline.

The grey seal can be seen bopping along in the water, before diving down to catch its prey.
