Status: No Conservation Concerns

This Opalescent Sea Slug (Hermissenda crassicornis) looks like it’s radioactive! It only reaches a length of about 50 mm, or 2 inches, but each inch is more beautiful than the next. So… it’s beautiful x 2 which = absolutely stunning! Man, I’m good at math.

You might be thinking that there’s no way those colors are real, especially the glowing blue that seems to radiate from within the sea slug. Is it a trick of the underwater photography? Excellent photoshopping skills? Nope. It’s just like that naturally … and I have video proof to prove it!


Now all I can hear is that epic Imagine Dragons song playing in my head… radioactive, radioactive! ♫
