What key observation led scientists to investigate the fusion phenomenon in comb jellyfish?
What key observation led scientists to investigate the fusion phenomenon in comb jellyfish?
- The disappearance of a jellyfish species from their lab, followed by the discovery of a larger, fused jelly. (correct)
- A sudden increase in the reproductive rate of the jellyfish.
- A significant decrease in the size of the laboratory's jellyfish population.
- The comb jellies developed the ability to change color.
What did the experiment reveal about the fused comb jellies' internal systems after they merged?
What did the experiment reveal about the fused comb jellies' internal systems after they merged?
- They each developed a second nervous system.
- They maintained separate digestive and nervous systems post-fusion.
- They shared a nervous system and stomach, acting effectively as a single organism. (correct)
- They developed a completely new nervous system.

Study Notes
- In October 2024, scientists discovered that two Comb Jellyfish had fused into one in their lab.
- The fusion is thought to be an adaptation to injury
- When scientists tested this, injured jellies merged within 24 hours
- The fused jellies share a nervous system and stomach.
- Though appearing as one, they retain separate, unique DNA.
- Researchers believe this is the first known case of organisms fusing together.
- This behavior is rare in the wild due to infrequent close proximity between comb jellies.
