Question

Carnivorous species which actively pursue their prey have:

• A. Prognathous mouthparts
• B. Hypognathous mouthparts
• C. Opisthognathous mouthparts
• D. Opisthorhynchous mouthparts

Hint:

Prognathous = forward-facing jaws = active predators.

Answer 1

The Correct Option is A

Step 1: Hypognathous and opisthognathous mouthparts point downward or backward, suited to feeding on a fixed surface, not chasing prey.
Step 2: Active hunters need mouthparts that project forward to seize prey while moving.
Step 3: This forward orientation defines prognathous mouthparts, seen in predatory beetles.
Step 4: The correct answer is prognathous mouthparts.
