Scientists have discovered recently that the Great White sharks can get much older than was thought previously.
It is quite hard to estimate the age of a shark as sharks have no bone, just cartilege.
Even so, in the vertebras there are some very indistinct 'year rings' that vary in density every season. Counting those the max age was determined to be at least 32 years.

Until they checked the rings for carbon isotopes.
The atomic bomb tests in the Pacific in the 50's and 60's of the previous century have left tell-tale deposits of heavy isotopes in the 'juvenile' rings of old male sharks, so now the scientists know that male Whites can reach an age of at least 73 years.

Of course, sharks are on top of the oceans food chain and may accumulate an aggravated amount of nuclear deposits because of that. Nevertheless it shows that these tests did have an impact on sea life, and while I doubt the phenomena described (*) are caused by the Fukusima accident, I cannot dismiss it as having no effect at all.

(*) Like the disected and dissolving sea stars which to me would seem the work of flesh eating bacteria.
