Summary:

- Researchers have discovered that certain species of comb jellies, which are marine invertebrates, have the ability to merge and form a single individual if they are injured.
- This process, known as "fusion," allows the comb jellies to regenerate and heal their damaged bodies by combining their remaining tissues and cells.
- The study provides insights into the remarkable regenerative capabilities of these organisms and could have implications for understanding tissue repair and regeneration in other animals.
