Brown land crab

Brown land crab key facts

Care level

Intermediate

Lifespan

Little data

Size

Carapace width up to 12 cm (males)

Diet

Omnivorous (mainly fallen leaves, fruit and seeds; sometimes insects or small animals)

Enclosure

Provide a large land area of damp substrate deep enough to dig in, and a water area the crab can fully submerge in. It is big and strong, so use heavy, stable water bowls and shelters.

Temperature & Humidity

Little data on keeping temperatures exist. It is a tropical to subtropical species, so avoid winter cold. It still breathes with its gills, so never let the enclosure dry out.

Diet & Feeding

Feed mainly plant matter such as leaf litter, fruit and vegetables, with occasional animal food.

Temperament & Venom

Not venomous. Mature males have one large claw that can injure, so do not pick it up bare-handed.

Notes

Land crabs are skilled escapers, so secure the lid. The larvae develop only in the sea, making captive breeding difficult. Never release captive animals, to avoid disturbing native populations.

7 things to know before welcoming a Brown land crab

1. 1A Large Crab, Up to 12 cm

   Adult males can reach up to 12 cm across the carapace, so this is a sizable land crab. Choose a roomy enclosure with plenty of floor space, planning for its full adult size. Crabs can slip out through small gaps, so use a lid that fastens securely.

2. 2Set Up Before Arrival

   Set up the enclosure before the crab arrives and check for a few days that temperature and humidity hold steady. Place a thermometer and hygrometer, and prepare the substrate, hides and water dish in advance. Care is rated intermediate, so give yourself plenty of time to get the setup right.

3. 3Deep, Diggable Substrate

   Many land crabs dig to hide, so a deep layer of moist substrate helps them settle in. Aim for a damp texture that holds its shape when dug. Add hides such as cork bark as well.

4. 4Humidity and Water Dish

   Even land crabs need to keep their gills moist, so don't let the enclosure dry out. Provide a shallow dish large enough for soaking and keep the water clean. Add an easy way in and out so the crab cannot drown.

5. 5Leaves and Fruit Diet

   This omnivore eats mainly fallen leaves and fruit. Offer leaves along with fruit and vegetables, and remove leftovers promptly, since they can mold and smell. Supplying a calcium source for shell building is a sensible extra.

6. 6Claws and Solo Housing

   Mature males grow one enlarged claw, and a pinch can cause injury. Avoid grabbing the crab with bare hands and use long tweezers or tongs for tasks in the enclosure. Crabs can fight each other, so keeping one per enclosure is the safer default.

7. 7Leave Them Be During Molts

   Crustaceans molt as they grow, and around a molt the shell is soft and easily damaged. The crab may stay buried and out of sight, so avoid digging it up or handling it, keep humidity steady and let it be. If it stops eating for a while, stay calm and check that nothing in the enclosure has gone wrong.

Frequently asked questions about Brown land crab

Q.Can a beginner keep one?

A.Care is rated intermediate. You need to manage humidity, a diggable substrate and escape-proofing all at once, so prior experience with other terrestrial animals or crustaceans makes it easier.

Q.How large does it grow?

A.Adult males reach up to 12 cm across the carapace, making this a large land crab. Choose an enclosure with its full adult size in mind.

Q.What should I feed it?

A.It is an omnivore that feeds mainly on fallen leaves and fruit. Offer leaves, fruit and vegetables, and clear away uneaten food regularly.

Q.Can I keep several together?

A.Crabs can fight, and a mature male's enlarged claw makes injuries more likely, so housing them singly is the safer default. If you do try a group, provide plenty of hides and watch them closely.

Q.How long does it live?

A.Little is documented about its lifespan, so there is no reliable figure. Assume a long commitment and make sure you can keep up the habitat before bringing one home.
