JACKSONVILLE, Fla. -- From coyotes to feral hogs to nutria, there are all kinds of non-native invasive species on the First Coast, but of the fiercest predators is one you don't see on land ... lionfish.

Joseph Kistel, Executive Director of TISIRI, a marine conservation organization, said lionfish likely ended up off the coast of Florida when aquarium owners turned them loose in rivers, canals and the ocean because they either got too big for the tank or ate all the other fish.

KEYSTONE HEIGHTS, Fla. -- Carnival Cruise Lines has seen its share of problems this year, but that did not stop Frances Prince and Mollie McCall from booking a seven day cruise.

"She wouldn't go without me and I wouldn't go without her," said Prince. 

But on May 9 Herb Green, McCall's fiance', was killed in an accident on State Road 16 near Starke. Prince is still trying to cope with the loss. 

Prince, McCall and Herb Green were good friends. 

"Tragedies happen," she said. "You can't schedule them."

On May 10, the day before they were to set sail, they contacted their travel agent with the bad news.

"Their big suggestion was see if you can find somebody else to take your place," Prince said.

Prince said she also called Carnival Cruise to try and reschedule the cruise.

PONTE VEDRA, Fla. -- Matt Kelly works as the caddy for PGA TOUR pro Marc Leishman. 

The Australian duo's star rose during their run at The Masters this year. 

Leishman finished in a tie for fourth place, but was in the group with eventual winner and fellow Australian Adam Scott.

"If it couldn't be my guy, it was cool to see another Australian win," Kelly said during an interview from TPC Sawgrass.

"There's been a lot of replays [of Adam Scott's win] and it's cool to see yourself in the background there," he said.

The background is generally where caddies find themselves in the course of a tournament. 

That's not a low blow, or a jab -- just the nature of their business. 

But Kelly said he's fine with that. It's a career path that introduced him to his girlfriend. They met at The Players. 

He even decided to move to Jacksonville Beach full-time from Australia to be closer to her.
