Green-eyed tree frog
Frogs are born with legs that are good for hopping and special pads on their toes to help them climb. In comparison, toads have shorter legs, drier skin, and are less likely to live near water. Most frogs and toads are responsible for controlling the Earth's insect population, since their diet consists mostly of insects and spiders. However, the green eyed-tree frog is also a carnivore. As a tadpole, the frogs mostly consume algae and plants. Frogs have a moist and permeable skin layer covered with mucous glands, which enables them to breathe through their skin, not just their lungs. The layer of mucus that covers them also acts as a shield, protecting them from scratches. The reason frogs have large and protruding eyes is to make up for their lack of a neck. This eye feature allows them to see everything around them. The color scheme of the green-eyed tree frog is to camouflage them from predators. Frogs with bright colors are alerting predators of their poisonous nature.
Megalodiscus temperatus
The reproduction of "Megalodiscus temperatus" are displayed in the stomach and rectum of frogs and tadpoles. The snails that are diffused with miracidia releases cercariae into the water to penetrate the skin of frogs. The frogs regularly cast off the outer layers of the skin which results in their exposure to metaceriae. The metaceriae remains in the rectum of the frog and matures in the time span of four months. Tadpoles are less commonly infected, but when infected they are infected by the ingestion of cercaria. Through the process of metaphorphosis, "Megalodiscus temperatus" travels primarily from the anterior to the posterior of the rectum.
