In which of the following animals post-anal tail is found?

  1. Earthworm
  2. Lower invertebrates
  3. Scorpion
  4. Snake

Answer

(4) Snake

Solution

As per NCERT, the fundamental characters of chordates are: a notochord, a dorsal hollow nerve cord, paired pharyngeal gill slits and a post-anal part (tail).

Earthworm (Annelida), scorpion (Arthropoda) and lower invertebrates are non-chordates, so they do not have a post-anal tail.

Snake is a reptile (Vertebrata, Chordata).

∴ Post-anal tail is found in snake.

Answer: (4)
