What are Gymnophiona?
Gymnophiona, also known as caecilians, are a distinct group of amphibians characterized by their limbless, worm-like bodies. They possess smooth, moist skin and are primarily adapted to a burrowing lifestyle, although some species are fully aquatic. Caecilians have unique features such as chemosensory tentacles on their heads, which aid in sensing their environment. They are less well-known than frogs and salamanders, largely due to their subterranean habits and are found mostly in tropical regions.

Examples of Caecilians
Caecilians are often overlooked due to their subterranean lifestyles, but several species illustrate the diversity within Gymnophiona. Ichthyophis is a genus that displays both terrestrial and aquatic habits, found in South Asia. Siphonops is known for its strong burrowing capabilities and is found in Central and South America. Typhlonectes, unlike its relatives, is fully aquatic and has adapted to live in water, showcasing the group’s versatility. These examples highlight the adaptability and range of habitats occupied by caecilians, despite their overall rarity in amphibian discussions.
