Investigators said one other night, the suspects hooked a nurse shark and left the line tangled in the dock without freeing the shark. "It's a real chore to get into a shark's mouth and get the hooks out. We were able to do that, but it could have been a lot worse if it had been left a long time," said Mark Perry with Florida Oceanographic. The state attorney's office is still deciding if the teens will be arrested and charged. Copyright 2015 Scripps Media, Inc. All rights reserved.
