Rare Princess Crab Sighted at Kaeng Krachan National Park
Phetchaburi, Thailand – July 31, 2025 — Officials at Kaeng Krachan National Park have confirmed a new sighting of the rare “Princess Crab,” also known as the Sirindhorn Crab, during routine monitoring activities at the Panenin Thung observation point.
The crab, noted for its distinctive deep purple coloration and white markings, was first captured in images by park rangers and released to the public this week. The species is named in honor of Her Royal Highness Princess Maha Chakri Sirindhorn, with the purple hue symbolizing Saturday, the day of her birth.
This crustacean is not only rare but ecologically significant. Experts regard the Sirindhorn Crab as a bioindicator species—its presence reflects the health and ecological balance of its habitat. The recent sighting suggests that the protected environments within Kaeng Krachan National Park continue to maintain strong ecological integrity.
Park biologists say they will continue monitoring the crab population and surrounding ecosystems as part of ongoing conservation efforts. Kaeng Krachan, Thailand’s largest national park and a UNESCO World Heritage Site, is home to diverse wildlife and is a focal point for biodiversity preservation in the region.
The crab was last photographed during official documentation work conducted by national park staff, who regularly track wildlife populations and environmental conditions in the area.
