West Island, Cocos Islands: the brown land crab (Cardisoma carnifex), a semi-terrestrial species of the family Gecarcinidae, inhabits coastal environments in the Indo-Pacific region, including the Cocos (Keeling) Islands, where it is abundant in saltmarsh areas and along lagoon fringes. Characterized by an oval-shaped, swollen carapace that is smooth and brown to brownish-gray in color, adults can reach up to 20 cm in carapace width, with males exhibiting one enlarged claw. These crabs construct burrows in moist soils to regulate osmotic pressure and humidity, emerging nocturnally or during wet periods to forage on plant matter, detritus, and occasionally small invertebrates. In the Cocos Islands, they play a role in nutrient cycling and are occasionally observed in forested areas. They are air-breathers that periodically immerse in brackish or saltwater to maintain ion balance but are not fully amphibious.

Christmas Island National Park: the Gecarcoidea lalandii, commonly known as the purple land crab or Andaman Islands purple crab, is a terrestrial species within the Gecarcinidae family that inhabits moist coastal forests and areas across the Indo-West Pacific region, including parts of Christmas Island where it is less common than its congener Gecarcoidea humei but can be observed in scattered locations. Adults grow to a carapace width of up to 160 millimeters, featuring a dark purple upper body that grades to cream underneath, with large rounded claws lighter in color. These crabs are opportunistic omnivores, feeding on carrion, insects, plant litter, seeds, fruits, and occasionally mammalian feces, while exhibiting behaviors akin to the island's red crabs, such as occasional participation in annual migrations to the sea for spawning. As obligate air-breathers in adulthood, they dig burrows in damp soil for shelter and rely on periodic access to water, facing potential threats from habitat disturbance and invasive species on Christmas Island.
