Question

what did sharks and rays develop that their ancestors did not have? amniotic eggs lobes that were the beginnings of arms and legs jaws that helped with catching prey legs to be able to survive on land

Explanation:

• Amniotic eggs are a characteristic of amniotes (like reptiles, birds, mammals), not sharks/rays.
• Lobes for limbs are related to tetrapod evolution, not sharks/rays.
• Sharks and rays (cartilaginous fish) evolved jaws, which their jawless ancestors lacked, aiding in prey capture.
• Sharks and rays are aquatic, so legs for land survival are incorrect.

Answer:

C. jaws that helped with catching prey
