Quiz Question: Which of these is the largest endangered fish on Earth?
The given options are as follows:
- Bluefin tuna
- Whale shark
The correct answer is: Whale shark
Fact: Averaging 20 tons, and growing as long as 32 feet, whale sharks are the gentle giants of the ocean. They are filter feeders, eating a variety of small marine critters such as plankton. Whale sharks are slow to mature, so reproduction of the species is slow, making their population highly vulnerable to overfishing that depletes their food supply, and to pollution incidents such as oil spills.
