Frogs and toads, as members of the class Amphibia, are commonly referred to as amphibians.

Frogs and toads belong to the order Anura, which translates to “No tail.” Further distinctions between frogs and toads are widespread and generally understood “From a taxonomic perspective, all members of the order Anura are frogs, but only members of the family Bufonidae are considered ‘true toads.’ The use of the term ‘frog’ in common names usually refers to species that are aquatic or semi-aquatic with smooth and/or moist skins, and the term”toad” generally refers to species that tend to be terrestrial with dry, warty or bumpy skin.

The 18th century biologist Lazzaro Spallanzani proved sexual reproduction can only take place through the joining of male and female gametes by putting rubber pants on frogs! It is often claimed frogs will allow themselves to be boiled to death if the temperature of water is raised gradually enough, but this is disputed by Douglas Melton, a Harvard biology professor: “If you put a frog in boiling water, it won’t jump out. It will die. If you put it in cold water, it will jump before it gets hot-they don’t sit. still for you.”

Frogs breathe with their lungs and through their skin to regulate moisture and fluid transfer.

We can “Help save frogs and other amphibians” by limiting the use of chemicals and pesticides which ultimately end up in the watershed and ultimately harm frog populations.
