Pictures of the starfish? People do it all the time, some people are going to RAP Orlando. I think if you just don't put a lot of air in the bag you should be okay.
I'm at work right now going to try to swing by the store before heading to the airport. it's a orange starfish nothing real special it's just only $10.
Since starfish will be difficult to tell if living you may have problems. I carried on clownfish a while back but they were swimming in the bag. I got anal probed by TSA as well so also keep that in mind.
