Respuesta :
Organisms in the category Amphibia relate to the Chordata phylum of the kingdom Animalia. These are multifunctional vertebrates that can live on land as well as in water. This class contains around 3000 species.
Characteristics of Amphibia?
The characteristics are:
- Eggs Unshelled
Living amphibians develop eggs that are very different from those produced by strictly terrestrial creatures such as reptiles. Because the amphibian egg lacks a calcified shell and is largely jelly, it is prone to fast desiccation if exposed to air.
- Permeable Skin
While caecilians have scales like fish, most other amphibians have moist, permeable skin. Most species are forced to survive in damp or aquatic settings; otherwise, they will quickly dry due to water loss through the skin.
- Adult Carnivores
While certain tadpoles and larval salamanders rely on plant and animal material, all adult amphibians are carnivores. While most amphibians eat invertebrates such as insects, arachnids, and earthworms, some also eat tiny vertebrates.
- Distribution
Amphibians can be found in most parts of the world, however, their global distribution varies widely from region to region. Most amphibian-rich places share a few traits, especially warm climates with substantial yearly rainfall.
- Rituals of Courtship
Frogs are well-known for their nocturnal choruses, which occur when males relocate to possible breeding sites and begin calling to attract females. When the females approach, the males wrap their arms around their backs and fertilize the eggs as they are laid.
