 The care of offspring among amphibians has been little studied but , in general , the larger the number of eggs in a batch , the less likely it is that any degree of parental care takes place . Nevertheless , it is estimated that in up to 20 % of amphibian species , one or both adults play some role in the care of the young . Those species that breed in smaller water bodies or other specialised habitats tend to have complex patterns of behaviour in the care of their young .
