A group of researchers procured some fish-like animals and upon investigation the following characters were observed: Which of the following species of animals did they consider to fit best with these characters ?

  1. Scoliodon sp.
  2. Exocoetus sp.
  3. Petromyzon sp.
  4. Branchiostoma sp.

Answer

(3) Petromyzon sp.

Solution

As per NCERT, cyclostomes are ectoparasites on some fishes; they have a sucking and circular mouth without jaws, a body devoid of scales and paired fins, 6–15 pairs of gill slits and a cartilaginous cranium and vertebral column.

All the observed characters fit class Cyclostomata.

∴ Petromyzon (Lamprey) fits best.

( Scoliodon – cartilaginous fish with jaws; Exocoetus – bony fish; Branchiostoma – cephalochordate.)
