The term "paraphyletic" refers to a group of organisms that includes an ancestor but not all of its descendants. In the context of vertebrates, both Reptiles and Fish are considered paraphyletic.

Reptiles are paraphyletic because this group includes all amniotes (animals that lay eggs on land or retain the fertilized egg within the mother) except birds and mammals. In other words, birds and mammals are descendants of reptiles but are not considered reptiles themselves.

Fish are paraphyletic because this group includes all gill-bearing aquatic creatures except tetrapods. Tetrapods, which include amphibians, reptiles, birds, and mammals, are descendants of fish but are not considered fish themselves.

Therefore, the correct answers are Reptiles and Fish.
