 The male Colostethus subpunctatus , a tiny frog , protects the egg cluster which is hidden under a stone or log . When the eggs hatch , the male transports the tadpoles on his back , stuck there by a mucous secretion , to a temporary pool where he dips himself into the water and the tadpoles drop off . The male midwife toad ( Alytes obstetricans ) winds egg strings round his thighs and carries the eggs around for up to eight weeks . He keeps them moist and when they are ready to hatch , he visits a pond or ditch and releases the tadpoles . The female gastric @-@ brooding frog ( Rheobatrachus spp . ) reared larvae in her stomach after swallowing either the eggs or hatchlings ; however , this stage was never observed before the species became extinct . The tadpoles secrete a hormone that inhibits digestion in the mother whilst they develop by consuming their very large yolk supply . The pouched frog ( Assa darlingtoni ) lays eggs on the ground . When they hatch , the male carries the tadpoles around in brood pouches on his hind legs . The aquatic Surinam toad ( Pipa pipa ) raises its young in pores on its back where they remain until metamorphosis . The granular poison frog ( Oophaga granulifera ) is typical of a number of tree frogs in the poison dart frog family Dendrobatidae . Its eggs are laid on the forest floor and when they hatch , the tadpoles are carried one by one on the back of an adult to a suitable water @-@ filled crevice such as the axil of a leaf or the rosette of a bromeliad . The female visits the nursery sites regularly and deposits unfertilised eggs in the water and these are consumed by the tadpoles .
