Which of the following is exclusively marine and considered as scavenger (feeds on dead or dying fish)?
Show Hint
Hagfish are jawless marine scavengers feeding on dead or dying animals, a unique ecological niche among fish.

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding scavengers.
- Scavengers are organisms that feed on dead or decaying organic matter in their environment.
Step 2: Marine habitat of hagfish.
- Hagfish are eel-shaped, jawless marine fish.
- They live in deep oceans and feed mainly on dead or dying fishes.
Step 3: Adaptations for scavenging.
- Hagfish secrete slime to deter predators.
- Possess rasping tongue to burrow and consume carcasses.
Step 4: Comparison with other options.
- Lamprey: parasitic, attaches to live fish.
- Lung fishes: freshwater, not scavengers.
- Latemaria (coelacanth): deep marine, carnivorous but not scavenger.
Step 5: Conclusion.
Hence, Hag fish is exclusively marine and a scavenger.
- Scavengers are organisms that feed on dead or decaying organic matter in their environment.
Step 2: Marine habitat of hagfish.
