increased egg interaction with steroids in seminal fluids, which may accelerate yolk metabolism and increase growth rate of tadpoles. Offspring as a result of polyandry are more likely to survive than offspring of monogamous matings. Fertilization Egg deposition primarily occurs in still, fresh water in order to keep the eggs moist during development. A typical clutch size can be anywhere between 500 to 1250 eggs. Grey foam-nest tree frogs strategically hang their foam nests on branches of trees above water at differing heights. Polyandry can positively impact fertilization success and offspring production in grey-foam nest tree frogs. This might be because more male mates ensures that the female’s eggs will be fertilized. A larger number of males means more sperm production, which therefore increases the likelihood the sperm are genetically compatible with the eggs and allows for a variety of different sperm-based traits. Female grey foam-nest tree frogs lay eggs which are quickly fertilized by the male soon afterwards. Females also create foam for nests. Grey foam-nest tree frogs show remarkable adaptability in their oviposition sites, as they may lay their eggs in a variety of unique habitats. They typically choose environments hanging over bodies of water, but if this is not possible, they lay eggs on any other suitable objects. Occasionally, they lay eggs directly in water or grassy vegetation above water. These tree frogs are more likely to choose lightly-wooded savannas and forested areas because these environments have sufficient resources to support adult frogs. Foam-nest building behaviors and patterns have evolved several times. The foam nest made by the female provides different functions for aquatic and terrestrial breeding alike. Some grey foam-nest tree frogs breed exclusively in water. In these water-breeders, foam nests allow the eggs to be suspended in oxygenated water. Grey foam-nest tree frogs that reproduce on land create these nests to minimize drying out, temperature changes, and predation. Development occurs over a period of six days, with the mother ensuring the eggs stay moist the day after mating. 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. Tadpoles live in the benthic zone (associated with or occurring on the bottom of a body of water). Maturity
