Researchers in Maldives obtain first ever underwater ultrasound scans of wild reef manta rays
A team of international researchers working with Six Senses Laamu in Maldives has obtained the first ever underwater ultrasound scans of wild reef manta rays.
The team of researchers from the University of Cambridge and the Manta Trust worked together with the Maldives Underwater Initiative (MUI) at Six Senses Laamu resort in the unexplored Laamu atoll to successfully scan a pregnant wild reef manta ray underwater to obtain clear ultrasound images of her foetus, using the world’s first contactless underwater ultrasound scanner.
Two years ago, MUI brought together some of the great minds in veterinary technology and challenged them to create a device that could ultrasound scan Laamu atoll’s resident population of reef manta rays (Mobula alfredi).
“MUI aims to be a marine conservation visionary,” Marteyne van Well, the General Manager at Six Senses Laamu, was quoted in a statement issued by Six Senses, saying.
“One of the ways we’re leading conservation efforts in the Maldives is by providing a platform for discussions on, and the field testing of, this world-first technology.”
Following a visit to Six Senses Laamu, Vetsonic (UK) Ltd Founder Ray Rochester approached veterinary imaging leaders IMV Imaging with the idea of developing a scanner to meet the rigours of diving at Manta Point, a manta ray cleaning station just a 10-minute boat ride from the resort that researchers from the Manta Trust have been studying since 2014.
IMV Imaging’s Duo-Scan:Go Oceanic is the first ever technology to allow contactless scanning of wild marine animals at depths of up to 98.5 feet (30 metres), whilst also being portable (the dive rig weighs less than 4.5 pounds (2 kilograms). The aim of bringing this technology to Laamu was to scan wild pregnant reef manta rays in order to study gestation and embryonic development.
“We know very little about where these reef manta rays go to give birth and how long gestation lasts in the wild. This ultrasound technology could allow us to determine rates of reproduction in the wild and this information would help guide conservation strategies for this threatened species,” Nicole Pelletier, Manta Trust Project Manager at Six Senses Laamu, said.
The research project is taking place in Maldives, which has the largest population of reef manta rays in the world. The team hopes that their work will help establish the factors responsible for annual fluctuations in breeding and discover why animals breed in certain areas but not others.
Manta rays are close relatives of sharks and rays. The largest individuals can reach as many as seven meters in width and weigh up to two tonnes. However, despite their size, and compared to some of their close relatives, mantas are gentle creatures.
Mantas are found throughout the tropical and sub-tropical oceans of the world. The animals never stop moving, as they must keep water flowing over their gills to respire. Their daily and seasonal movements are tuned to the ebb and flow of the ocean currents that carry the planktonic food upon which they depend.
“Manta rays are one of the most beautiful and iconic creatures that swim in our oceans,” Dr Gareth Pearce, from the Department of Veterinary Medicine at the University of Cambridge, was quoted in a statement issued by Manta Trust, as saying.
“Unfortunately, like many animals, their future is threatened. They are increasingly fished, both deliberately and through bycatch and their populations are now at risk.”
In recent years, manta ray populations have become threatened through bycatch in fisheries targeting other species, such as tuna and swordfish, but also because their gill plates have recently become sought after for use in Asian medicine.
Working with the Manta Trust, Dr Pearce and PhD student Niv Froman use the new ‘Duo-Scan: Go Oceanic’ ultrasound scanner to study the reproductive ecology of manta rays. To scan the manta rays, researchers dive down to a ‘cleaning station’ where smaller fish remove parasites from the mantas’ skin. These stations are typically 20-30 metres down, often with poor visibility and potentially strong ocean currents.
The diver then approaches a manta from above to avoid disturbing the animal. He positions the scanner 4-5cm above the surface of the manta, targeting the left side of the dorsal fin, which is where the reproductive structures such as the ovaries and the uterus are visible.
“It’s important not to cause the manta ray any stress,” Froman explained.
“Using these portable scanners, we’re able to obtain ultrasound images of their internal structures, particularly their reproductive tracts, without disturbing the animal. This is the first time that this has been possible in free-swimming mantas.”
The scanner enabled the team to obtain the first-ever scans of wild reef manta rays, including pregnant and non-pregnant females, as well as mature males.
“Using the scans, we’re able to determine the stages of maturity and when animals are becoming reproductively active. We can observe the stages of pregnancy, the development of the foetus and importantly, whether an animal maintains that pregnancy and gives birth to a live animal,” Dr Pearce said.
“Ultimately, our work aims to inform the conservation of manta rays both in the Maldives and other areas of the world, enabling the populations to survive and hopefully flourish. Our hope is that this research project will contribute to conserving the species for future generations.”
Sightings of the animals in the Maldives are reliable and consistent, allowing the researchers to take images of the same animal multiple times throughout its gestational period, which lasts just over a year.
“When the project began, none of the team knew whether scanning wild reef manta rays would even be possible. What has been achieved is beyond what we could have hoped for,” Dr Guy Stevens, Co-Founder and Chief Executive of the Manta Trust, said.
“Manta rays are threatened worldwide and we still know so little about their reproductive strategies. The ability to scan pregnant individuals will be invaluable in our quest to protect them.”
According to IMV-imaging, the ‘Duo-Scan: Go Oceanic’ represents significant improvements on previous technologies. It can be taken to depths of up to 30 meters and —with the assistance of Wi-Fi and a smartphone as a viewing screen—it is small enough to fit in the palm of your hand.
“What we are really excited about is the contactless nature of this technology. There are significant benefits for animal welfare, but you also open up a whole range of possible applications if you can scan animals that ordinarily wouldn’t let you get close enough to touch them,” Alan Picken, Chief Executive of IMV-imaging, said.
The Cambridge researchers, in collaboration with a team from the Manta Trust, verified that the contactless technology works in the field tests carried out in collaboration with the Vetsonic (UK) Ltd and Six Senses Laamu.

Cinnamon Hotels & Resorts Maldives has won three awards at the South Asian Travel Awards (SATA) 2026, with Cinnamon Dhonveli Maldives and Cinnamon Velifushi Maldives receiving recognition across three categories.
Cinnamon Dhonveli Maldives secured Gold in the Leading Surf Resort category for the eighth time and fourth consecutive year, while Cinnamon Velifushi Maldives retained Gold in the Leading Beach Resort category for the second consecutive year. Cinnamon Velifushi Maldives also received Silver in the Nishan Seneviratne Best CSR Programme category.
The 10th edition of SATA was held at Barceló Nasandhura Malé on 8 October 2026, recognising achievements across South Asia’s tourism and hospitality industry, including guest experiences, industry leadership and responsible tourism.
Located in North Malé Atoll, Cinnamon Dhonveli Maldives is home to the Pasta Point surf break, which attracts surfers from around the world. The resort’s eighth Gold award in the Leading Surf Resort category reflects its position among the Maldives’ surfing destinations. In addition to surfing, the resort offers water sports, wellness activities and other guest experiences.
“We remain committed to delivering memorable surf experiences and holidays in the Maldives,” said Marlon Robert, General Manager of Cinnamon Dhonveli Maldives.
