There are some key differences between caecilians and other species of amphibians.
Many amphibians can exchange oxygen through their skin via a specialized membrane, but caecilians do not.
Their skin is quite thick, and they must come to the surface to take breaths of air.
Our caecilians are five months old. Since they are juveniles, they take breaths more frequently, about every five to 10 minutes.
Adults, however, can hold their breath between 20 to 30 minutes at a time.
