I have a question sir : Why apoda are include in tetrapods although they have no legs.

[@Om._.shantii]

Some have lost their limbs due to evolution like snakes. Another reason is that their most of characters are similar with other members so we cannot neglect those characters. Like presence of bones, nerves,, vertebral column. Remember exception is everywhere due to different lifestyle😊
