This important evolutionary step occurred several times independently in the tropics and subtropics and produced convergent adaptations in the life history [...] With a further advancement into terrestrial habitats, the crabs colonised habitats with small aggregations of water that became nurseries for larvae and juveniles, for example the shells of large land snails and leaf axils of bromeliad plants filled with rainwater.
