Public warned not to disturb Lyme Regis dolphin
The arrival of a dolphin in Lyme Regis has delighted residents and visitors, but the authorities warn people are getting too close to the animal.

A solitary bottlenose dolphin has become a regular visitor to Lyme Regis harbour to the delight of residents and visitors. However, marine wildlife bodies, conservation authorities and the police are issuing a warning to the public following direct observation, reports, and video of people intentionally approaching the animal too closely.
While seeing dolphins in the wild is undeniably a special experience, irresponsible behaviour such as swimming, paddleboarding, jet-skiing or operating watercraft near them can place the animal, or yourself, at risk.
In fact, dolphins, whales and porpoises are protected by law, as the Marine Management Organisation (MMO) and Dorset Wildlife Trust are keen to remind the public.
Under the law, it is an offence to intentionally approach or recklessly disturb these animals and could result in up to six months in prison and/or an unlimited fine.
Sergeant Ryan Prater of the Dorset Police Marine Unit said: “We are fortunate here in Dorset for people to be able to visit and enjoy our spectacular Jurassic Coastline.
“This coastline is home to many species of marine animals and wildlife, and as we go into the busy summer season, it is important that those visiting our beautiful coastal areas consider the wellbeing of marine wildlife and take steps to prevent any unnecessary disruption.
“In recent years, we have seen whales, seals, dolphins and other unexpected marine wildlife appear on our coastlines and so it is important that the public keep a safe distance from them. Protecting our coastline is something we take very seriously, and we will continue to work closely with our partners – including the Marine Management Organisation – to ensure marine animals are able to live safely in their natural environment, free from human disruption.”
If you encounter a dolphin when you’re on the water, you should:
- Slow down and keep speed below six knots (no-wake speed).
- Stay at least 100 metres away and slowly move further away if you notice signs of disturbance.
- Keep your distance if there are already more than two boats or watercraft in the vicinity.
- Never encircle or chase animals.
- Never try to swim with, touch or feed them.
Sometimes dolphins may choose to approach you. In this situation, you should maintain a steady speed and direction and let the animals leave when they choose.
Jess Churchill-Bisset, head of Marine Conservation (wildlife), said: “The arrival of a dolphin in a small coastal community like Lyme Regis can be a source of wonder and pride. But it’s vital to remember that dolphins are vulnerable and unpredictable wild animals protected by law.
“We all have a responsibility to respect their space, keep a safe distance, and understand how our actions can unintentionally cause harm or even constitute a criminal offence. By giving these animals space, observing them from a distance and acting responsibly we help ensure their health and survival, so they remain a part of our coast now and for generations to come.’’
Anyone who has information or concerns about wildlife crime or disturbance should report it to the police. If a wildlife crime is happening now, call 999. Otherwise, information can be provided by calling 101 and saying “‘Operation Seabird” to report marine wildlife disturbance. or using the form on the Dorset Police website.
