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 feature of amniotes (like reptiles, birds, mammals), not sharks/rays (cartilaginous fish), so this is incorrect.
• Lobes for limbs are related to tetrapod evolution, not sharks/rays.
• Sharks and rays (cartilaginous fish) evolved jaws (from gill arch modifications) to help catch prey, which their jawless ancestors lacked.
• Sharks and rays are aquatic, don’t have legs for land survival.

Answer:

C. jaws that helped with catching prey
