A lone bottlenose dolphin – This is a well known dolphin that has been named Clet. He is well known and was first documented in France. In recent years he has spent time on the South Devon, Cornish, Isles of Scilly and Welsh coasts. It is important to be very careful when around lone bottlenose dolphins, they often choose to interact with boats, but poor/thoughtless boat handling can lead to them being severely injured or even killed. It is not advisable to swim with them as they are much more powerful than you and have a habit of trapping people in the water. Always keep in mind that they are not your plaything.

Internationally famous dolphin turns up in Scotland

An internationally famous solitary Bottlenose Dolphin known as Clet has been identified making a surprise appearance in Scotland’s Sound of Mull, according to researchers from the Hebridean Whale and Dolphin Trust.

The rare sighting of a lone bottlenose dolphin following a ferry between Oban and the Isle of Mull triggered some rapid detective work at the conservation charity.

Bottlenose dolphins are not unusual in the Hebrides, even during winter – but the species usually occurs in small groups, with individuals rarely being seen alone.

By studying the dolphin’s distinctively scarred dorsal fin and using photo identification techniques, the Trust’s experts identified the animal as one that made international headlines with its unusual behaviour when it was last seen in September. That was in Galway in Ireland, some 600 kilometres away from the Sound of Mull.

“To our knowledge, this is the first time that Clet has been recorded in Scotland, and in fact this is the furthest north he has been recorded to date,” says Dr Conor Ryan, Sightings Officer at Hebridean Whale and Dolphin Trust.

“Bottlenose dolphins are usually considered to be resident to certain areas, so long-distance international movements such as this one has made challenge our understanding of this species, and also challenge our ability to protect them using Marine Protected Areas alone.”

The male dolphin was named by locals from Cap Sizun, Brittany in France, where he habitually follow[ed] the fishing boats between 2008 and 2010. He then travelled to Cornwall, Devon and Wales before appearing in West Cork in Ireland and spent several weeks interacting with boats.

The Irish Whale and Dolphin Group then recorded his movements along Ireland’s west coast to Valentia, County Kerry.

The last recorded sighting of Clet was on 28 September 2014 at Inis Óirr off Galway Bay. Although not confirmed, he was thought to be responsible for a dolphin attack on a group of swimmers in Salthill, Galway.

The RNLI ensured that the swimmers were able to get to shore without harm, but unfortunately the incident resulted in some sensational news headlines.

Solitary dolphins such as Clet do not pose a threat to people in boats, but can be aggressive towards swimmers.

The biggest danger to solitary dolphins is injury from boats, as the animals appear to seek out vessels to interact with. The deep gash on Clet’s dorsal fin may be from coming to close to boat propellers.

Pádraig Whooley, Sightings Officer for the Irish Whale and Dolphin Group, says: “We think it’s remarkable that Clet’s movements can be tracked to the Irish south and west coasts from France via English and Welsh waters, using images from the general public.

“The addition of Scotland after a two-month interval brings his known tally of passport stamps to five countries and counting, and shows the need for international collaboration when trying to monitor these highly mobile marine mammals.”

Wildlife photographer Nic Davies, who recorded Clet close to shore from Craignure on the Isle of Mull this week, said: “I was out photographing otters when I heard a loud blow sound just out from the shore, and then I spotted the dolphin heading at speed towards a departing ferry.”

Clet may remain in the Sound of Mull area for weeks or even months, as he has done in other areas. Hebridean Whale and Dolphin Trust is asking boat owners to be respectful and to give Clet the space he needs.

That way, hopefully the dolphin will continue to enthral onlookers from the shore and from the ferries he has been bow riding in the Sound of Mull.

Hebridean Whale and Dolphin Trust asks the public to report sightings of all whales, dolphins and porpoises – collectively known as cetaceans – and basking sharks at www.hwdt.org.

The charity’s extensive Community Sightings Network uses such sightings as a key way of strengthening understanding of the local marine environment and of these spectacular animals.

New Marine Protected Area in Bangladesh

First ever Marine Protected Area for Bangladesh

Bangladesh has created its first marine protected area that will now safeguard whales, dolphins, sea turtles, sharks, and other oceanic species.

Bordering the territorial waters of India, the Swatch of No Ground Marine Protected Area (SoNG MPA) spans some 672 square miles (1,738 square kilometres and is more than 900 meters deep.

The waters are home to large numbers of Irrawaddy Dolphins, Finless Porpoises, Pacific Humpback Dolphins, Indo-Pacific Bottlenose Dolphins, Pantropical Spotted Dolphins, Spinner Dolphins, and what may be a resident population of Bryde’s Whales.

“The SoNG MPA supports an astonishing diversity of dolphins, porpoises and whales including species in need of immediate protection,” said Rubaiyat Mansur of the Wildlife Conservation Society’s Bangladesh Cetacean Diversity Project.

“Declaration of Bangladesh’s first Marine Protected Area shows our country’s commitment to saving its natural resources and wonders.”

The Wildlife Conservation Society’s Bangladesh Cetacean Diversity Project has worked along with the Government of Bangladesh since 2004 to ensure the long-term protection of the cetaceans (whales, dolphins, and porpoises) in waters of Bangladesh through collaborative efforts with local communities.

“Marine protected areas that conserve cetaceans and other marine life are extremely important steps in saving vital marine ecosystems that support hundreds of thousands of people,” said Dr. Howard Rosenbaum, Director of the Wildlife Conservation Society’s Ocean Giants Program. “Safeguarding these species and natural resources will become even more important in the years to come, particularly due to the challenges of climate change.”

Dolphins attracted by magnets?

New study finds dolphins may be attracted to magnets

The behaviour of six bottlenose dolphins were analysed in the study.

A study undertaken by researchers from the Ethos unit at the Universite de Rennes in France has revealed that dolphins could be magnetoreceptive, which means they have the ability to perceive a magnetic field.

In the wild, the ability of marine mammals to follow migration routes suggests that they might be sensitive to geomagnetic fields, but until now there has been no experimental evidence to confirm this.

Research was conducted at the delphinarium of Planete Sauvage in Port-Saint-Pere, France, and looked at the behaviour of six bottlenose dolphins in response to two separate barrels. One barrel contained a strongly magnetised block, and one contained a demagnetised one. Apart from this detail, the blocks were identical and indistinguishable to the dolphins when they used echolocation.

The dolphins were seen to approach the barrel containing the strongly magnetised block much faster than they approached the barrel with the unmagnetised block. In order to ensure a fair experiment, the dolphins were free to swim in and out of the pool were the barrel was placed, and the person placing the barrel in the pool, and analysing the videos of the dolphins’ reactions, did not know which barrel was magnetised.

Dorothee Kremer, a researcher in the experiment, explains the importance of the study’s findings: “Dolphins are able to discriminate between objects based on their magnetic properties, which is a prerequisite for magnetoreception-based navigation. Our results provide new, experimentally obtained evidence that ceteaceans have a magnetic sense, and should therefore be added to the list of magnetosensitive species.”

Abu Dhabi dolphins research

Indo-Pacific Humpback Dolphins at Tin Can Bay, Queensland, Australia

Indo-Pacific humpback dolphins, also known as Chinese white dolphins, are a common sight around the northern parts of Australia. In Australia, you can interact with these cool cetaceans at Tin Can Bay, and if you want, you can even feed them for $5.

In Abu Dhabi, like in Bahrain, there are human rights violations.

However, like beautiful dolphins swim off Bahrain, dolphins swim off Abu Dhabi as well.

Results from Abu Dhabi dolphin survey revealed

The Environment Agency – Abu Dhabi (EAD) recently undertook the first vessel-based survey of dolphins in coastal waters of the Emirate of Abu Dhabi as part of its new Dolphin Conservation Programme, which has the goal of monitoring the Emirate’s dolphin population and supporting their long-term conservation.

The survey identified two species; the Indo-Pacific Bottlenose dolphin, and the Indo-Pacific Humpback dolphin. In total, 77 bottlenose were recorded, of which 19 were calves, and 61 humpback, of which 10 were calves. The team also sighted two new born calves, which could indicate that dolphin calving season might occur late spring to early summer in Abu Dhabi.

The 15-day survey – which was conducted in partnership with the Bottlenose Dolphin Research Institute in Spain – was carried out using a custom-made 45-foot boat fitted with an observation platform, and covered 2,000km of Abu Dhabi’s coastal waters, extending from Sila Peninsula in the west to the border of Dubai in east.

The team used photo-identification, taking high-definition images from cameras mounted on drones, in order to identify and track individual dolphins by looking at the unique markings on their dorsal fins. From this they were able to determine the population size.

Results revealed that there were regional differences in which species of dolphin was most dominant: around EAD’s Marawah Marine Biosphere Reserve, Indo-Pacific humpback dolphins were more prevalent, while bottlenose were the most common from Al Dhabbaiya to Ras Ghanadah, and between Al Sila and Sir Bani Yas Island.

Commenting on the survey, Director of Marine Biodiversity at EAD Ayesha Yousef Al Blooshi said: “The data collected from the survey will support us in further developing our conservation initiatives for our marine biodiversity, as well as helping us conserve the natural heritage of Abu Dhabi for future generations.”

Dolphin populations might be seeing better days ahead in Jamaica as the Government aims to implement new regulations on the use of the animals for tourism purposes, addressing the trading of dolphins and their use for attractions: here.
