The spores of ferns and mosses lodge and germinate in the crevices of tree bark on rainforest trees, covering them with lush growth. These later form pockets of compost in which orchids and bromeliads grow. Bromeliads are related to the pineapple and each has its own population of animal lodgers. Various animals make use of the bromeliads' leaves to shelter in and the pools of water trapped at their heart are frequented as a useful drinking spot for canopy animals. Several species of poison arrow frogs use the pools in bromeliads as tadpole nurseries. Most regard their parental responsibility as over once they've dropped their tadpoles in the pool. But one species returns to lay more eggs in the pool, but these aren't fertilised - they're merely a food for the existing tadpoles.
