Scientists using holiday snaps to identify whale sharks

Maldives Promotion House – Holidaymakers’ photos could help scientists track the movements of giant endangered sharks living in the waters of the Indian Ocean. A new study, led by a researcher from Imperial College London, is the first to show that these publically sourced photographs are suitable for use in conservation work.

Tourists scuba diving and snorkelling in the Maldives frequently take underwater pictures of the spectacular and docile whale shark, often called the world’s largest fish. Conservationists have long hoped to use this photographic resource to help them trace the sharks’ life history, relationships and geographic distribution, although the value of these amateur snapshots has never been properly measured.

Tim Davies of Imperial’s Division of Biology is the lead author on a study published in Wildlife Research, the first to examine how reliable photographs sourced from the public actually are. He and his team did this by comparing results using tourist images with results based on surveys by marine researchers specifically aiming to track the sharks.

In order for a shark to be clearly identified, any photograph must capture the distinctive pattern of spots located directly behind the gills. This unique marking serves as a ‘fingerprint’, which can then be scanned with a computer programme to tell the animals apart.

The study looked at hundreds of images taken by the public, of which many were downloaded from image-sharing websites such as Flickr and YouTube. Individual whale sharks could be successfully identified in 85 per cent of cases, surprisingly close to the 100 per cent identification possible in photographs taken by researchers.

Speaking about the results, Davies said: “Globally, this outcome provides strong support for the scientific use of photographs taken by tourists for whale shark monitoring. Hopefully, this will give whale shark research around the world confidence in using this source of free data. In the Maldives in particular, where whale shark tourism is well established and very useful for collecting data from throughout the archipelago, our results suggest that whale shark monitoring effort should be focused on collecting tourist photographs.”

Although they are widely thought to be rare, the conservation status of the whale shark has long remained uncertain. This study therefore allowed the team to measure the populations of whale sharks in the area, which they estimate have not declined in recent years. Davies added: “Hopefully, as more data come in from tourists over the years and from further across the archipelago, we will be able to build up our understanding of the Maldives population and monitor its status closely.”

Holidaymakers can assist researchers in monitoring whale shark populations by uploading their shark photos to the ECOCEAN whale shark identification library website (www.whaleshark.org).

Sun Siyam Iru Fushi has introduced an exciting new activity for ocean enthusiasts: Conservation Snorkelling. Led by the resort’s resident marine biologist, Mohamed Shah, this immersive experience allows participants to contribute to marine conservation efforts while exploring the vibrant underwater ecosystem of the Maldives. Combining education, exploration, and action, the initiative offers an enriching opportunity for visitors of all ages.

Participants engage in collecting critical data on coral health and fish populations using underwater fish guides, coral health charts, and writing slates, while learning to identify various fish species. They assess reef conditions and contribute to the protection of the local marine environment. The findings are then discussed with Mohamed Shah, providing deeper insights into the marine life of the Iru Fushi lagoon and house reef.

This activity is a key component of Sun Siyam Cares, the resort’s initiative focused on environmental protection and community support. Families, young couples, and other guests can participate in global conservation efforts through the Coral Watch citizen science project. The activity is open to strong swimmers aged eight and above who feel comfortable snorkelling.

“At Sun Siyam Iru Fushi, we strive to protect the stunning natural environment around us,” said Abdullah Atham, Resort Manager. “Through activities like Conservation Snorkelling, we encourage guests to explore and actively contribute to ocean conservation.”

The week-long Active Escapes Maldives Festival will be held from 27 April to 4 May 2025 at the private island resort. This event is set to be the largest Active Escapes event of the year, attracting those who enjoy combining energetic recreation with a serene holiday atmosphere. Prices for the retreat start from US$2,600++ per person, twin share.

Sharon Garrett, Director of Marketing at Holiday Inn Resort Kandooma Maldives, expressed excitement about collaborating with Active Escapes again in 2025. “The week-long retreat-style festival offers a unique mix of adventure and relaxation. It’s perfect for individuals who prioritise health and fitness while on vacation or are looking to start fresh,” she said.

Garrett further noted, “It’s not a boot camp where you feel deprived of all the enjoyable aspects. On an Active Escapes retreat, guests can indulge in delicious cuisine prepared by the resort’s talented chefs and enjoy an impressive drinks list. The concept is to work out hard during the day and reward yourself in the evening.”

Active Escapes curates experiences that cater to a wide range of preferences, from water-based activities like snorkelling and kayaking to scuba diving and more. In addition to aqua-centric pursuits, there is also time for holistic well-being. This includes yoga sessions against the backdrop of breathtaking sunrises or sunsets, visiting the Kandooma Spa by COMO Shambhala in the resort gardens, or simply taking a moment to relax and reflect by the beach with the soothing sounds of the waves. Active Escapes emphasises both the thrill of leisure pursuits and group fitness activities, as well as the tranquility and balance that can be achieved by embracing nature’s beauty and being present in this island paradise.

The Active Escapes Maldives Festival 2025 is all about having fun and attracting people from all around the world. It’s not solely for fitness enthusiasts; on the contrary, it offers a welcoming environment where the goal is for participants to leave a bit fitter than when they arrived in the Maldives, although the ultimate decision on participation level is up to them. There are varying degrees of difficulty in the program to ensure that those seeking a more intense workout feel challenged, while those needing a less intense workout are well catered for.
