Yes. Caecillians are of the subclass lissamphibia, which includes anurans (frogs), Urodellans, (salamanders) and gymnophiona (caecillians) The taxonomic progression is as follows:
Kingdom: Animalia (not plants, protists, etc.)
phylum: chordata (possessing of a spinal chord)
subphylum: vertebrata (possessing of a backbone)
superclass: tetrapods (tetrapod means four limbs)
class: amphibia (both fossil and extant amphibians)
subclass: lissamphibia (extant amphibians)
Caecillians lost their legs secondarily, that is, their ancestors had legs and their progression toward an increasingly fossorial (burrowing) lifestyle created a selection pressure toward the loss of legs. The clues to this lie in the pectoral girdles where their legs used to articulate. They have a heavily ossified skull for digging, a specialized jaw which locks so they don't get mouthfuls of dirt while digging. They have ribs but they don't encircle the body.
many worms are also fossorial but they are in the phylum annelida, not chordata. They have converged on very similar body styles as a result of congruency in their lifestyle.
Hope this clears things up.
Caecillians.

Caecillians are amphibians.
Animals that breathe through moist skin are amphibians , frogs, salamanders, caecillians , newt , snail , earthworm , etc
Yes they do. All frogs, salamanders and Caecillians have lungs. However the tadpoles do not and develop lungs in the time that they live in water.

Cranial bones are bones of the head, tarsal bones are bones of the feet.
There are often sesamoid bones at the interphalangeal joints resembling the petella in the knee
There are irregular bones, these bones are your vertebrae
There are 5 types of bones in the human body. There are long bones, short bones, flat bones, irregular bones, and sesmoid bones.
The body consists of long bones, flat bones, irregular bones, short bones and sesmoid bones. The short bones include bones in the wrist and foot.
Bones classified into four groups. Long bones,Short bones,Flat bones, and Irregular bones
