I was watching a video about white-tip reef sharks and they are a perfect reef predator at night. They can detect the slightest muscle movement of fish hiding on the reef so I was wondering if they also eat lionfish. It seems that lionfish would be easy prey for white-tip reef sharks because they are slow and white-tip reef sharks swim through all the nooks and crannies searching for prey. There are no white-tip reef sharks in the Caribbean so that might be why there are high numbers in the Caribbean? Just a thought.
