Leiopelmatidae, or New Zealand and North American primitive frogs, is a family belonging to the suborder Archaeobatrachia. There are only four Leiopelma and two Ascaphus species alive now. Leiopelma are only found in New Zealand. Ascaphus are only found in North America.
When Leiopelmatid jump, they land in a "belly flop". After landing, Ascaphus skids to a halt before recovering.
They are very small frogs, only 5 centimetres (2.0 in) in length. Most species lay their eggs in moist ground, typically under rocks or plants. After hatching the tadpoles nest in the male's back. They do not need standing or flowing water. Life span may be long at more than 30 years.
