Question

Which of the following organisms have no exoskeleton?

• A. Frog
• B. Scorpion
  
• C. Cockroach
  
• D. Shrimp
  

Answer 1

The correct option is A Frog

• An exoskeleton is a hard shell-like structure that protects the organism from the outside.
• The presence of an exoskeleton is a characteristic feature of the phylum Arthropoda.
• Being an amphibian organism the frog can live in both land and water, hence the body of a frog is built in such a way that it aids in swimming and jumping, so they do not possess an exoskeleton.

Therefore, the correct answer is option A.
