When a lobster releases a claw, what typically happens to the lost appendage?

• A. The lost claw immediately grows back to its original size.
• B. The lobster permanently loses the ability to use that side.
• C. The lobster cannot survive after losing a claw.
• D. The lobster can regenerate the lost claw over time.

Answer: (D)

Verified step by step guidance

1. Understand the concept of regeneration: Regeneration is the biological process by which organisms replace or restore lost or damaged tissues, organs, or appendages. Many crustaceans, including lobsters, have the ability to regenerate lost body parts over time.
2. Identify the specific case of lobsters: Lobsters are known for their ability to regenerate lost claws or other appendages. This process is gradual and occurs during subsequent molting cycles, which are part of their growth and development.
3. Clarify the molting process: Molting is the shedding of the exoskeleton to allow for growth. During molting, lobsters can regenerate lost appendages, including claws, although the new claw may initially be smaller than the original and grow larger with subsequent molts.
4. Eliminate incorrect options: Review the provided choices and eliminate those that contradict biological facts. For example, lobsters do not permanently lose the ability to use one side, nor do they immediately grow back a claw to its original size. Additionally, losing a claw does not prevent survival, as lobsters can adapt and regenerate.
5. Conclude with the correct answer: Based on the biological understanding of regeneration and molting, the correct answer is that the lobster can regenerate the lost claw over time.
