Bottlenose Dolphin - photo identification

Powerful, social and increasingly seen off the Yorkshire coast. A pod of bottlenose dolphins now ranges down from Scotland and is regularly spotted from Bempton Cliffs and Flamborough Head. Look for the tall curved dorsal fin and the rolling, unhurried surfacing of a group moving together.

Bottlenose dolphins live in tight social groups. A 'pod' will often hunt cooperatively, herding mackerel and herring against the surface. Sightings off the Yorkshire coast have increased dramatically over the past decade - thought to be linked to warming seas and shifting prey.

Even alone, a dolphin's tall, slightly hooked dorsal fin is unmistakable. From the cliffs at Bempton on a calm day, scan the line where the swell catches the light - that flash of dark fin breaking the surface is often the first clue.

A spectacular double breach - one adult clear of the water in a full arching leap, the second rising vertically alongside in a shower of spray. Bottlenose dolphins breach for several reasons: communication, displacing parasites, courtship play and pure exuberance. Watch for the powerful tail flukes and the rounded melon (forehead) that houses the dolphin's echolocation system.

How it fits into North Yorkshire wildlife

Dolphins are part of the wider North Sea story that reaches the North Yorkshire coast. They reflect the condition of open water, fish stocks and the health of the marine food chain beyond the cliffs and beaches people know best.

How it interacts with the wider landscape

As predators, dolphins sit near the top of the system. Their fortunes are linked to fish abundance, clean water, underwater noise and the condition of the smaller prey species below them.

Seasonal rhythm

Sightings can happen at different times of year, often where fish are concentrated or sea conditions briefly make the surface easier to read from shore or boat.

Where to look and what to notice

Look for fast, smooth surfacing offshore, curved dorsal fins and coordinated movement through feeding areas along the coast.
