3. These traits look similar but have a different purpose. Limbs for walking in humans but swimming in dolphins.
6. Scientists hypothesized that these organisms were the first living things in the ocean over 3.5 billion years ago.
8. the acronym for the Endangered Species Act
9. the most endangered marine animal. There are less than 10 left.
10. When two different species have a common ancestor. Dogs and wolves.

13. this petroleum based material is used in a lot of products like straws, forks, and bags.
15. a species that is in immediate danger of extinction.

19. the main theory of how life began. This hypothesis states that life started from nonliving inorganic sources.
20. When similar organisms show differences in heritable traits.

1. the protection and preservation of marine ecosystems through planned management.
2. These traits look different but serve the same purpose. Fish have fins and penguins have wings but they are both for swimming.
4. when two completely different species have similar adaptations like bats and birds both having wings.
5. a species that has been reviewed and is now being proposed to be threatened or endangered.
7. a species that is likely to become endangered in the near future.
12. The acronym for a Turtle Excluder Device. These devices are 97% effective at safely allowing sea turtles to escape from trawling nets.
14. The creation of a new distinct species from environmental factors or hybridization.
17. a species not listed but is undergoing a review.
18. this invasive species of fish is native to Indonesia.
