No fishermen have worked these waters since the last evacuation of Rongelap (Rongelap Atoll in the western Pacific which was contaminated by nuclear weapons test in the 1950s) in 1985, and with fewer human predators fish have flourished. Remoras, lithe scavengers that feed on a wide variety of aquatic life, appear healthy too, exhibiting no ill effects from what little radioactivity remains in the food chain.

I've been floating around in the ocean for 50 years, and I've never seen so many remoras in one place before, says Teddy Tucker, a deep-sea fishing expert. I'd shake some bait out of my bag and they'd be all over me my back, my arms, my legs. Fortunately remoras rarely bite. Sharks, on the other hand, require a less intimate approach.
