About Parathelphusa reticulata Ng, 1990
Parathelphusa reticulata, commonly known as the swamp forest crab, is a critically endangered species of freshwater crab that is endemic to Singapore. This species reaches a maximum size of 40 mm, or 1.6 inches. Parathelphusa reticulata is found exclusively in Singapore, and has only ever been recorded in Nee Soon Swamp Forest. However, starting in 2019, researchers successfully bred two generations of this crab. They released 20 individuals into the wild at a new, undisclosed nature park, and released the remaining captive-bred crabs back into Nee Soon Swamp Forest. This crab lives in freshwater swamp forests with water that has a low pH between 5.0 and 5.5. It digs burrows along the edges of muddy banks, is highly secretive, and is only active at night. It feeds primarily on plant matter, but will also scavenge animal matter when the chance arises.
