Caeciliadae is a family of legless amphibians commonly known as caecilians. There are many other synonyms for this word, such as Gymnophiona, Apoda, and Ichthyophiidae. Caecilians can be found in tropical regions worldwide and are characterized by their long bodies, lack of limbs, and their ability to burrow in soil. They primarily feed on invertebrates such as earthworms and termites. Although they are not as well-known as other amphibians like frogs or salamanders, caecilians play an important role in their ecosystems and their conservation is crucial for maintaining biodiversity.
