Answer 2

Answer:

Ductus caroticus is present in the order Squamata and sub-order Lacertilia of the class Reptiles

Ductus caroticus is nothing but a particular blood vessel that joins individual carotid arches with the systemic arch on that side of the body of these reptiles. The most common reptile that possess ductus caroticus is lizard. Lizards possess a well-defined and properly formed ductus caroticus. One interesting feature of the ductus caroticus is that it vanishes in the embryonic stage or the early stages of development of the reptiles.
