The Brighton Dolphin Project has a Research Programme so we can learn more about dolphins and other marine wildlife in Sussex. This is achieved by:
Conducting research into local dolphin / wildlife populations through a Public Sightings Database.
Studying our impacts on the marine environment.
Whilst Dolphins are not spotted daily off the Sussex Coast, the areas you are most likely to see dolphins include:
Newhaven and Newhaven Harbour
Adults can grow to 1.9-3.9m long. They have a large grey body, a pale grey or pinkish belly and a tall sickle shaped dorsal fin. Bottlenose Dolphins are commonly seen in groups of 2-15 individuals, however large groups and single dolphins are not uncommon. These animals are playful and curious, and are often seen bow riding the waves of boats and leaping clear out of the water.
Common dolphins have a characteristic figure of 8 pattern on their flanks which is tawny/yellow, brown, grey and black. They have a white belly and a sickle shaped dorsal fin. They are between 1.7-2.5m long. Common dolphins are a highly active species. They are fast swimmers and regularly ride the bow waves of boats.
A large, sturdy dolphin that can grow to 3m in length. They have distinctive pale grey-white flashes along the flanks and a pale grey patch behind the dorsal fin known as a saddle patch. They have a dark grey back, tail and pectoral fins. Their dorsal fin is tall, and sickle shaped and their beak is usually although not always pale grey or white. White-beaked dolphins are fast swimmers, acrobatic and they often ride the bow waves of boats. They are most often spotted in groups of between 5-20 individuals but can form larger groups.
They grow to between 1.4 to 1.9m in length. They have a stocky body, a small rounded head that lacks a beak and a triangular dorsal fin that has a blunt tip. The body is a dark grey which lightens on the flanks and their underside to light grey or white. They are most often seen in groups of 2-5 individuals, however they are also sighted alone. Harbour porpoises are known to be elusive and will rarely approach boats. They generally travel quite slowly and tend to be sighted in relatively inshore waters and coastal regions
Dolphins and porpoises display a range of interesting and exciting behaviours:
Bow riding: Dolphins often swim in the pressure wave formed ahead of boats which are pushing through the water.
Slow travel: Dolphins maintain a steady speed by only raising the upper parts of their body as they surface.
Porpoising or running: Dolphins can travel at a high speed by leaping clear of the water.
Chorus lines: Pods of dolphins often change direction as a unit and can swim in a line formation.
Remember: Dolphins are wild animals. If you are lucky enough to encounter them at sea, keep your distance and be respectful.
Report Your Sightings
If you do see any dolphins we would love to know, and we'd be grateful to receive photos and videos. This will allow us to learn more about these charismatic animals living just off our coastline!
Student Research Projects
We do welcome students who are studying their Bachelors or Masters to complete their research dissertation project with us. If there is a particular subject that you would like to investigate, please do get in touch with details about your proposal and how it will benefit the Brighton Dolphin Project.
