NEOBATRACHIA

'Neobatrachia' are a suborder of order Anura, i.e. of frogs or toads. As the name suggests, this suborder, of the three, is the newest (''neo''-). It is also the largest, with more than 5,000 different species making up over 96% of all frogs.
The differentiation between Archaeobatrachia, Mesobatrachia, and Neobatrachia - which is a bit controversial, and as more research is done and more knowledge is gained is even becoming less clear, because many characteristics used for this differentiation apply to more than one group - is mainly based primarily anatomic differences, especially the skeletal structure as well as several visible characteristics and behaviors. Neobatrachia are generally sorted into four superfamilies - although this division is also controversial, as some families are classified into different superfamilies, depending on who is asked. They are usually classified into the following four superfamilies:

★ Bufonoidea

★ Hyloidea

★ Microhyloidea

★ Ranoidea
