Glass frog moms do care after all

摘要

Glass frogs often start life with some tender care from a source scientists didn't expect: frog moms. Maternal care wouldn't be news among mammals or birds, but amphibian parenting intrigues biologists because dads are about as likely as moms to evolve as the caregiver sex. And among New World glass frogs (family Centrolenidae), what little parental care there is almost always is dad's job—or so scientists thought, says Jesse Delia of Boston University.
