October 17th marks an important day on our calendars where we highlight one of our oceans most marvellous creatures – International Sawfish Day. First launched four years ago, this day is dedicated to increasing knowledge and awareness of one of the most endangered groups of elasmobranchs.
As long-time supporters of sawfish research and conservation efforts, we’re joining the celebration to highlight their wonder, their role in keeping our ecosystems healthy and balanced, and the threats they face. This International Sawfish Day, we’ll be sharing interesting resources and fun facts about these saw-snouted fishes on social media throughout the day.
Sawfishes are some of the oceans’ most intriguing creatures, growing up to 7 m in length with a saw-like snout, known as the rostrum. Their prehistoric and other-worldly form may have you thinking they belong in the deepest parts of the ocean, however, this shark-like ray species prefer warm coastal waters and is often found in murky rivers. Due to their decimated populations and preference for turbid river waters, sawfishes have kept the scientific research community on their toes for years, as they can be extremely difficult to find and collect data on. These slow-breeding, long-lived creatures are heavily overfished for their meat and fins, and their rostra (the saw) often get them tangled in fishing gear. Furthermore, their habitats continue to disappear as coastal areas become increasingly developed.
Over the last 16 years, SOSF has funded over 25 projects dedicated to sawfish around the world. We aim to highlight their threats and to work with communities to make sure we don’t lose sawfish entirely.
SOSF is proud to be a part of the solution with seven project leaders out in the field this year, trying to crack the code on sawfishes mysterious lives.
Andros Island: a lifeboat for sawfishes? Sawfishes are rapidly disappearing from our seas, so when a healthy population was discovered off Andros Island in The Bahamas, the area became a very important place. Dean aims to understand this rare community of sawfishes in order to protect them.
The Sawfish Sleuth – Tonya is searching for clues as to how and where smalltooth sawfish populations might begin to recover in the Tampa Bay Area should they have some protective measures in place.
Tracing sawfishes in the last habitats of Costa Rica – Mario is using traditional fishing techniques in combination with eDNA (traces of sawfish DNA left behind in the environment) sampling to document where the last habitats for sawfishes can be found in Costa Rica.
Juan Cubillos Moreno
Searching for ‘El Guacapa’ with eDNA – Juan is collecting eDNA samples from the estuaries and mangroves of Colombia’s Chocó region with the aim of learning more about where exactly the critically endangered largetooth sawfish occurs. Known locally as ‘El Guacapa’, they are typically found in estuaries and thought to be resident in some of Central and South America’s freshwater systems. Knowing exactly where this sawfish occurs is critical to its conservation.
Filing in the gaps for Ghana’s shark fisheries – By trawling the fish markets and landing sites of Ghana’s coastline, Issah is surveying the patterns in catch composition over time for sharks and rays in artisanal fisheries. In doing so, he is also raising awareness about the best fishing practices that safeguard sharks and rays and garnering fishers’ support for sharks and the conservation of ocean ecosystems in Ghana.
Alifa Binta Haque
Honing in on habitats – Annual encounters with the four sawfish species found in Bangladesh are reported to have been declining drastically over the past five years. Alifa is training local fishers to help map where these Critically Endangered species were found and what habitat is essential for their survival today.
Bridging the gap – From research to conservation for sawfishes in Bangladesh – Ruth is aiming to develop educational and awareness-raising tools to reach fishing communities in Bangladesh, and highlight that they can become stewards of one of the last remaining populations of largetooth sawfish in the world.
A new use for old things: saving sawfishes with repurposed rostra – Veronika is giving old sawfish trophies a new lease on life by constructing 25 educational cases that will be displayed across Far North Queensland. In doing so, she is hoping to transform these rostra into a symbol of hope and caution that connects communities to the conservation of sawfishes.

SOSF keystone project leader and top international sawfish researcher Ruth Leeney advises that we should support organisations at home as well as those that are working in low-income countries through donations. By helping them to continue their focused and informed work on-the-ground to address local issues you can make a real difference for the animals and the people who share their habitat.
