A sea turtle clutch. A clutch of eggs is the group of eggs produced by birds, amphibians, or reptiles, often at a single time, particularly those laid in a nest. In birds, destruction of a clutch by predators (or removal by humans, for example the California condor breeding program) results in double-clutching. The technique is used to double ...
The eggs are deposited into large temporary ponds which form because of the rainy season. Their clutch size is typically around 400 eggs per clutch. These eggs will hatch 36 hours after fertilization. Immediately after hatching, the frogs will remain motionless in a vertical position with their head up under the water.
Reproduction occurs in the rainy season. Egg clutches are deposited on vertical surfaces of boulders and plants above water, occasionally away from water in areas that get subsequently flooded. [1] The female frog guards the clutch after laying. Scientists have observed mother frogs jumping on grasshoppers that presumably wish to eat the eggs. [5]
[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 ...
In some species, the male frog will periodically return to the clutch and moisten the eggs with urine from his bladder. For example, the male poison arrow frog Phyllobates vittatus sits on top of his eggs and sheds liquid. He visits the clutch roughly three times each day until hatching. [2]
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 and 1250 eggs. Grey foam-nest tree frogs strategically hang their foam nests on branches of trees above water at differing heights. [5]
Clutch Predation. In the Central Amazonia, tree frogs of the genus Phyllomedusa lay their eggs in gelatinous masses on leaves and branches over water. 59% of tiger-striped tree frog clutches are often attacked by predators such as phorid flies (being the majorly responsible for clutch loss), and other unidentified predators. The reason for ...
There are usually between 676 and 2720 eggs in a single clutch, with an average of about 1278 eggs per clump. [3] The Italian agile frog's eggs have thinner gelatinous layers – only 6 to 7 mm (about 0.24 in) – than those of other species of frogs. The minimum water temperature for egg deposition is reported as 2 °C, and eggs hatch after 10 ...
