How cool are starfish? They have no brain, they can regenerate, and when you flip them upside down they're like, "Screw this, I'm flippin' myself back over!" But turns out they also really, really like their privacy.
A recent study in the journal of the National Centre for Biotechnology Information found that starfish have a pretty cool way to avoid microchip tags.
When Danish biology students Frederik Christensen and Trine Olson tried implanting the asterias rubens (common starfish) with microchips, they found the creatures would simply draw them through their bodies internally before "spitting" them out from their arms. Outrageous.
And the most impressive part? It doesn't even harm them to do it. Starfish are magic!
