Quiz Question: Which of these is the largest endangered fish on Earth?
The given options are:
- Whale shark
- Bluefin tuna
- Coelacanth
Correct Answer:
Whale shark
Info: Averaging around 18 tonnes, and growing as long as 39ft (12m), 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.
