Mesobatrachia is a suborder of frogs, encompassing diverse species often found in aquatic or semi-aquatic habitats. Known for their intermediate evolutionary features, they exhibit a range of reproductive strategies, unique vocalizations, and diverse body sizes. Many species play crucial roles in controlling insect populations.

Mesobatrachia is not a single species, but rather an infraorder of amphibians that includes various families and species. The infraorder is primarily distributed across regions in Europe, Asia, Africa, and the Americas. Members of Mesobatrachia can be found in diverse geographical areas, including central Europe, parts of Asia such as China and Japan, sub-Saharan Africa, and parts of North and South America.

Mesobatrachians inhabit a wide range of environmental conditions due to their broad distribution. They are typically found in moist environments such as marshes, swamps, and forested areas with abundant water sources. Some species can be found in temperate regions, while others thrive in tropical climates.

The ecological niche of Mesobatrachia species varies significantly due to the diversity of the infraorder. Generally, these amphibians play a critical role in their ecosystems as both predators and prey. They help control insect populations and serve as food for larger predators. Their presence is often indicative of a healthy wetland or aquatic ecosystem. Some species have adaptations for burrowing or living in semi-aquatic environments, allowing them to exploit specific ecological niches within their habitats.
