Scylla serrata

Mangrove crabs are common in the mangrove ecosystems found in Sri Lanka and other tropical regions around the world. They can grow up to 25 centimeters in width and have a dark brown or olive-green shell with distinctive whitish markings.

Mangrove crabs are omnivorous and feed on a variety of food sources such as leaves, fruits, insects, and small animals. They play an important role in the ecosystem as scavengers and are also a source of food for many predators, including humans.

Mangrove crabs are also commercially important in Sri Lanka, and they are caught for food and export. However, overfishing and habitat destruction are threatening their populations, and it is important to manage their populations sustainably to maintain the health of the mangrove ecosystem.
