World Tomistoma Day, observed every year on August 5, is dedicated to raising awareness about the Tomistoma, also known as the false gharial. This endangered crocodilian is native to Southeast Asia, particularly Malaysia and Indonesia. The day was designated in 2016 by the Tomistoma Task Force under the IUCN Crocodile Specialist Group, in memory of conservationist Ralf Sommerlad. Zoos, researchers, and wildlife enthusiasts are marking the day by highlighting the importance of protecting this elusive species, which faces growing threats from habitat destruction and human conflict.
Global Outreach and Education
Zoos around the world have become strong advocates for Tomistoma awareness. Institutions like Crocodiles of the World in the United Kingdom and San Antonio Zoo in the United States have previously hosted educational talks, live feeding sessions, and special exhibits for World Tomistoma Day. These events assist in engaging audiences with information about species behavior, ecological role, and endangered status on the IUCN Red List.
The hashtag #WorldTomistomaDay is being used in more and more social media campaigns to encourage people to share images, facts, and conservation messages. The website crocday.org provides information and updates for the event, encouraging people to check local zoos for event postings or to engage online.

Conservation Progress and Challenges
A few conservation successes have occurred recently. In May 2024, the Virginia Aquarium received Tomistoma hatchlings, a sign of progress in behavioral endpoint in breeding programs. The Bronx Zoo, in January 2024, re-entered the international conservation for Tomistoma to focus on captive breeding as it marked its first successful hatching in forty years.
However, there are still challenges. The current estimation of the wild population ranges from 2,500 to 10,000 mature individuals. Their habitats, mainly peat swamp forests in Borneo, Sumatra, and Peninsular Malaysia, are shrinking due to logging, palm oil expansion, and human settlement. The species has likely disappeared from Thailand and possibly Java.
A 2022 report documented 31 human-Tomistoma conflict incidents in Indonesia over a decade, with a fatality rate of more than 30 percent. As a response, conservationists are working on community-based strategies like crocodile exclusion enclosures. The Tomistoma Task Force has also held training workshops in Sumatra and Kalimantan to empower local researchers and strengthen conservation action.

Tomistoma Conservation at a Glance
| Aspect | Details |
|---|---|
| Population | 2,500 to 10,000 mature individuals (IUCN Endangered) |
| Habitat | Peat swamp forests, rivers, and lakes in Borneo, Sumatra, and Peninsular Malaysia |
| Conservation Status | Endangered, facing habitat loss and human encroachment |
| Recent Breeding | Hatchings at the Virginia Aquarium in May 2024, the Bronx Zoo in January 2024 |
| Threats | Logging, palm oil plantations, and human-wildlife conflict |
World Tomistoma Day 2025 serves as a timely reminder of the need to conserve lesser-known endangered species through education, captive breeding, habitat protection, and ongoing fulfillment of regional conservation goals around the globe to secure a future Tomistoma, or false gharial.
Engagement with the public, whether through social media, visiting zoos, or showing interest or supporting conservation aims, is integral to our success and to preventing this species from disappearing quietly.
