This is a crab that digs burrows in the riverbanks and shorelines it lives on to hide from predators and the sun. Adults eat leaves and seeds, removing them from the surface and hoarding them in their burrows.

The ideal system for them is a small terrarium or riparium.

The decapod crustaceans of Estero el Verde. Note the white spots towards the rear of the carapace. They live mostly on leaf litter and other vegetation, but are omnivores and will eat just about anything as long as it’s fresh. They also need a consistent source of calcium, so take this into account when feeding them.


The planktonic stage in this species lasts for at least a month, following which young crabs settle and develop in coastal habitats. A riparium more exactly fits the habitat they come from, and a small terrarium would still have to incorporate some water. This nocturnal crab digs burrows — sometimes as long as 1. Gecarcinus ruricola has darker, purple limbs and a purplish carapace without ‘eyes’. The species preferentially feeds on the seeds of particular types of plant, favouring the persistence of some at the expense of others.

The Halloween crab has an apparently completely black actually dark brown when examined closely upper carapace, a bright orange-red body and limbs and purple claws. Forgot your username or password?

In other projects Wikimedia Commons. Because of their small natural range, they don’t need a lot of space, but that space does need to be very clean.

Decapoda Brachyura – Crabs Class: They need a pretty consistent temperature f and water heaters or subterranean heaters are a good way to manage this. Primarily mangroves and lowland rainforest, often along river banks. By doing they play an important role in structuring forest habitat where they occur see Ecology. It has a pair of largely purple clawsred-orange legs, and an almost entirely black carapace with a pair of yellow, orange or reddish spots behind the eyes, and an quadratys pair of quaxratus spots on the central-lower carapace.


The patterning of this crab is unique, particularly the auadratus of quacratus claws and orange-red limbs. Not Listed Carapace Length: The taxonomy in relation to the Atlantic G. Gecarcinus quadratus De Saussure These mechanisms have the overall effect of reducing tree density and diversity in forests where the crab occurs.

The crabs can occur at high densities, up to 6 per m -2and the removal of large quantities of leaf litter from forest topsoils influences carbon storage and nutrient cyclingreducing the carbon and mineral content of the topsoil and enriching lower soil layers.

Gecarcinidae – Land Crabs Order: The Halloween crab is an ecosystem engineer. The crab itself is an important food source for raccoons Procyon lotor where the species occur together.
