A decomposing marine mammal - thought to be a harbour porpoise - was discovered on a beach this morning.

The carcass was discovered by a passer-by in Whitstable on the shoreline at about 11.15am today near the RNLI station.

Beth Winter from British Divers Marine Life Rescue said: "I believe the marine mammal in the picture is unfortunately a harbour porpoise and looks as if scavengers have got to it."

According to Kent Wildlife Trust, harbour porpoises can be spotted close to shore in relatively shallow water, especially in tidal races and around headlands.

There are thought to be around 340,000 living in and around the North Sea

The charity states: "They are usually solitary or in small feeding groups of up to 10. They are pretty shy and will avoid boats and jetskis - though they are known to be more curious in some areas around the UK.

"Harbour porpoises give birth to a small calf every one to two years, normally in early summer.

"Look out for a small, triangular dorsal fin breaking the surface. Harbour porpoise are small and stocky, with a dark grey back and lighter underbelly. Their faces are rounded and have no beak."

A spokesperson for Canterbury City Council said: "We're grateful to KentOnline for alerting us to this. We will visit to arrange recovery and disposal as soon as we can get someone there."
