Reproduction

The Pacific Giant Glass Frog reproduces by the male first finding the perfect spot. Then he fights off any other males that try to take over. He waits there and calls for a female. The females comes over to the males spot and he climbs on her back. This piggyback postion is called amplexus. The male stays on her back untill she lays the eggs. 24-36 eggs can be laid at a time. The gestation period is 60 days and they can live up to 6 years. They are "r" because they produce more then 5 young and they go off not taking care of the eggs.

Threats

Some of the threats that made the frogs disappear are global warming, temperature changes, and having a less cloudy sky makes the weather to dry for frogs. People are cutting down forests and there are fires that also destroy the forest. If this keeps happening they will become extinct. A soultion is if there was an unlimited amount of rainforests then the frog would live there becuase it is moist and wouldn't dry out the frog's skin.

Role in the Ecosystem

Frogs keep the bug population to a minimum and keep the ecosystem in balance. And they are a food source for larger animals. They are consumers because they other frogs. Some examples of other organisms in the same ecosystem are moths, dragonflies, and ants.

Nutrition

The glass frog eats many insects and some fish and even other frogs. So it is a carnivore and gets its energy from the meat it eats.

Habitat

They live in Rain forests and Cloud forests. Mostly because it has a lot of rain and it is very humid. That way they can have there tadpoles in some source of water. It is located in South America. Abiotic factors are 150 inches of rain fall, 70-100 degrees, and 80% humidity most of the time. Some Biotic factors include animals, like monkeys, lions, and iguanas.

They like to live high in the mountain cloud forest from 5,740-9,840 feet above sea level, because they prefer forests with shade, waterfalls, or rapids.
