I am glad to see they are addressing this problem in Negril. We saw 8 Lion Fish on our first snorkel on the cliffs and had to choose an alternate exit point, as the ladder out was surrounded with them. I am thankful they were not there when we entered the water, as I wouldn't have known it until too late. :-{

They are such a beautiful creature, but so invasive. I understand their sting is pretty nasty as well.
I still found snorkeling the cliffs to be so enjoyable, but would love to see these guys thinned down to nothing.
