Lionfish have become an invasive species since their introduction into the Atlantic Ocean, where they have few natural predators due to their venomous spines and quick reproduction. They feed voraciously on native reef fish and mollusks, negatively impacting coral reef biodiversity. How can scientists further investigate the characteristics and impact of lionfish in order to develop potential solutions to this issue?

Capture lionfish and study their spines in a laboratory
Study the lionfish in their natural habitat in the Pacific Ocean
Study maps of lionfish sightings prior to 1995
Use a remotely operated underwater vehicle (ROV) to capture lionfish

As mentioned in the question that lionfish is considered to be highly dangerous due to their fierce and veracious life style. In order to know more about the characteristics and impact of lionfish in order to develop potential solutions to the issue is to:

- Capture lionfish and study their spine in lab

- Study their life style in their natural habitat

This will help us to improvise ways that could help us protect other fishes from lionfish and also help us to develop a safe environment for the other marine animals.
