Welcome to the wondrous world of frogs! These fascinating creatures are not only an essential part of various ecosystems but also a subject of immense scientific intrigue due to their unique anatomy and physiology.
The external structure of a frog is designed to optimize their life in water and on land. Frogs have smooth, moist skin that assists in their unique method of breathing through their skin, also known as cutaneous respiration. Their powerful hind legs are adapted for jumping and swimming, making frogs excellent at both.
Internally, frogs are just as intriguing. They possess a three-chambered heart, which is quite different from the four-chambered hearts of mammals. This allows for a fascinating flow of oxygen-rich and oxygen-poor blood.
