- A something becomes larger it is able to act upon more of something else
- Fins move animals through water by pushing against water
- Hence, the larger and animal's fin is, the more water it can push against

- The larger and animal's fin is, the more water it can push against
- The more water an animal's fin pushes against, the faster that animal will move through water
- Therefore, the larger an animal's fin is, the faster it can move through water

- The larger an animal's fin is, the faster it can move through water
- Fins are a part of aquatic animals used for moving through water
- Hence, large fins can be used to move quickly through water

- If an organism 's prey moves quickly then that organism may need to move quickly to catch its prey
- A predator is a kind of organism
- So, if a predator's prey moves quickly then that predator may need to move quickly to catch its prey

- If a predator's prey moves quickly then that predator may need to move quickly to catch its prey
- Eating prey requires catching prey
- So, some predators move quickly to catch prey

- Large fins can be used to move quickly through water
- Some predators move quickly to catch prey
- Therefore, large fins can be used to move quickly through water in order to catch prey

Therefore, large fins can be used to move quickly through water in order to catch prey
