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.
During the first day the eggs on the female's back will sink into the skin and by evening will be set into the back of the female. Two days later, the yolks of most of the eggs are beneath the skin level and only parts of the jelly and outer membranes of the eggs are visible on the backs above.
Frogs may lay their in eggs as clumps, surface films, strings, or individually. Around half of species deposit eggs in water, others lay eggs in vegetation, on the ground or in excavations. [ 136 ] [ 137 ] [ 138 ] The tiny yellow-striped pygmy eleuth ( Eleutherodactylus limbatus ) lays eggs singly, burying them in moist soil. [ 139 ]
Hydric brooding is an egg incubation practice performed by some species of frogs. It involves either placing urine from the bladder on the eggs to keep them wet or holding the body over the eggs to prevent them from drying out. [1] [2] [3] [4]
When it is time, the males migrate to the water. They then make a call at the same time. This lures the females to the water, where they mate. The females lay their eggs in clumps of 10–90, and usually put them on and under vegetation and leaf litter in the pond. Females usually lay their eggs in shallow, calm water that has little action ...
The feeding habits of the frogs is that of a modified sit-and-wait forage mode. This means that they will sit and wait for food to arrive, similar to ambush predators. These frogs were observed to stay within a range of 5 cm from the entrance of the burrow and at the end of their foraging period rapidly dart back into the burrow.
[13] During this breeding period, an egg clutch consisting of 1000 to 7000 eggs [11] is laid in surface films about 15–30 cm in diameter and are attached to vegetation in shallow water [14] in order to protect the eggs from predators. Females may sometimes lay two clutches of eggs in a single season, with their size reaching a maximum of 98 ...
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.
