The two main shapes for the microhylids are wide bodies and narrow mouths and normal frog proportions. Those with narrow mouths generally eat termites and ants, and the others have diets typical of most frogs. Egg-laying habits are highly varied.
The Surinam toad, despite its common name, is actually native to several South American countries; as well as Suriname, it is known from Brazil (primarily the states of Acre, Amazonas, Mato Grosso, Pará and Rondônia), Bolivia, Colombia, Ecuador, French Guiana, Guyana, and Venezuela, in tropical rainforest regions to the east of the Andes.

[ 136 ] [ 137 ] [ 138 ] The tiny yellow-striped pygmy eleuth ( Eleutherodactylus limbatus ) lays eggs singly, burying them in moist soil. [ 139 ]
Egg mortality in foam nesting tree frogs remains mostly unexplored, therefore information regarding the matter is limited. Grey foam-nest tree frogs' egg mortality is considered moderate compared to other anuran species. Following the embryonic development, a tadpole breaks free and drops into the water below the foam nest.
The frogs may move up to 100 m during amplexus before the female lays her eggs. [36] During the laying of the eggs, the pair of frogs remain in amplexus and the male is assumed to fertilise the eggs with his sperm. Males are also seen to paddle their rear legs during this time, which is speculated to accelerate fertilisation. The egg-laying and ...

About 18–30 eggs could be laid, and the male frog would stand guard over the eggs to protect them from predators until they hatch, and the tadpoles drop into the water. [9]
The announcement of the frog's return comes two years after a conservation effort began to bring them back to the archaeological site that was home to the Mississippian culture of Native Americans ...
Therefore, laying in warmer ponds increases the reproductive fitness of the frog.The frog would also prefer ponds that persist for an intermediate period of time because laying eggs in a pond that persists for a long time risks the introduction of a large number of predators to the eggs while short-lived ponds have too few as well as carrying ...
