Answer: Shark
======================================================
Further explanation:
- Whales are not fish. This is a common misconception many people have (the same goes for dolphins as well). Whales are mammals that don't have gills, which is why they occasionally come to the surface for oxygen.
- Despite "fish" being literally right in their name, jellyfish aren't fish. It's confusing I know. Jellyfish belong to the phylum Cnidaria, while fish belong to the phylum Chordata.
- Octopus aren't fish either. They are molluscs and are related to animals like snails, squid, and slugs.
- Sharks are fish. They have gills and fins like any other fish does.
