Mangrove crabs are crabs that live in and around mangroves. They belong to many different species and families and have been shown to be ecologically significant by burying and consuming leaf litter. Mangrove crabs have a variety of phylogenies because mangrove crab is an umbrella term that encompasses many species of crabs. Two of the most common families are sesarmid and fiddler crabs. They are omnivorous and are predated on by a variety of mammals and fish. They are distributed widely throughout the globe on coasts where mangroves are located. Mangrove crabs have wide variety of ecological and biogeochemical impacts due to the biofilms that live in symbiosis with them as well as their burrowing habits. Like many other crustaceans, they are also a human food source and have been impacted by humans as well as climate change.

Aratus pisonii, commonly known as the mangrove tree crab, is a species of crab which lives in mangrove trees in tropical and subtropical parts of the Americas, from Florida to Brazil on the Atlantic coast. A.pacificus occurs from Nicaragua to Peru on the Pacific coast. A. pisoni feeds mostly on the leaves of the mangroves, but is an omnivore, and prefers animal matter when possible. A. pisonii and A. pacificus are the two species in the genus Aratus. The specific epithet pisonii commemorates the Dutch naturalist Willem Piso who travelled in Brazil in 1638 with Georg Marggraf.

The wharf crab is a small crab that is dark brown to muddy in color, which allows it to blend in with its usual surroundings.

Parasesarma messa, commonly known as the maroon mangrove crab, is a species of burrowing crab found in Queensland, Australia. It lives in mangroves in estuaries and sheltered bays. It was originally described as Sesarma messa, but was placed in the genus Parasesarma in 2017. Perisesarma messa is also a synonym.

It inhabits the Western and central Indo-Pacific ocean, including Singapore, Malaysia, Australia (Queensland), the Philippines and New Guinea. Tioman crabs are supralittoral. In Cairns, Australia they are known for moving in numbers in some seasons entering backyards and homes. This species was originally described by H. Milne Edwards in 1837 as Sesarma indicum. It was placed in a new genus Tiomanium by Serene and Soh The carapace is convex and 34 mm length. Key features that differentiate Tiomanium from Neosarmatium include a spine at the end of the upper inner margin of the cheliped palm and a spine on the upper inner angle of the carpus.
