context_page_description: The smallest organisms found on Earth can be determined according to various aspects of organism size, including volume, mass, height, length, or genome size.
  Given the incomplete nature of scientific knowledge, it is possible that the smallest organism is undiscovered. Furthermore, there is some debate over the definition of life, and what entities qualify as organisms; consequently the smallest known organism is debatable.
context_section_description: The smallest vertebrates (and smallest amphibians) known are Paedophryne amauensis frogs from Papua New Guinea, which range in length from 7.0–8.0 mm (0.28–0.31 in), and average 7.7 mm (0.30 in). Previously, the title of smallest vertebrate was held by members of the fish genus Paedocypris of Indonesia.
