2. Real-life Thumb Trick

You know that classic party trick where you pretend to remove your thumb, only to reveal it's still intact?

No sleight of tentacle here: Brittle stars employ this adaptation called autotomy as a defense mechanism against predators, regrowing their lost limbs like aquatic magicians, minus the hats and rabbits.

3. Ocean Superheroes

4. Sea-rious Comeback

Breaking up is hard to do, but not for the Brittle Star's limbs: they've got regrowing arms down to a fine art. Channeling their inner starfish sorcery, these creatures laugh in the face of danger, being all like, "Yeah, go ahead, take my arm – I'll grow another one!" And they do: when a brittle star's arm is lost or damaged, it can regenerate a whole new limb, provided the central disk remains unharmed, which can take a matter of weeks or even months. That's what you call a sea-rious comeback!

6. Britney Spears of the Sea

As Britney Spears might say, "Oops, I did it again!"—when it comes to escaping predators, brittle stars ain't no amateurs: They commit autotomy, detaching and sacrificing an arm on purpose, which continues to wriggle and distract the enemy while our five-limbed friend regenerates with a brand new appendage.

7. Clark Kents of the Ocean Floor

Brittle stars should be called the Clark Kents of the ocean floor: they might not boast the most conventional eyes, but they've got some rather super vision beneath their red, photoreceptor-rich skin. However, when they lose their beaming red façade and go incognito in beige mode, they're just like any other ordinary sea creature, stripped of their amazing visual prowess. Funny how that works, right?: Ophiocoma wendtii, a species of brittle star, is capable of changing its color to increase vision resolution by limiting the angles of light entering its photoreceptors, but loses this ability when it transitions from red to beige.

8. Marine Wolverine

Brittle stars are basically the marine world's Wolverine: they possess rapid regeneration powers that put comic book superheroes to shame! This sturdy sea dweller can quickly regrow lost limbs or even its entire central disk (filled with vital organs) in just a few months: In some species, this regeneration occurs at a ridiculously fast rate of up to 1cm per day. Marvelous, isn't it?
