Answer:
The correct option is lamprey.
Explanation:
Lamprey is a kind of fish which lack jaws. They lack a true skeleton, but the cartilage is present in them. Due to lack of proper backbone, they look similar to snails. The lamprey reproduces by laying eggs in the water. Larvae tend to develop from these eggs. The lamprey releases its eggs only in freshwater.
