Sea Star Regeneration

Sea stars have an amazing ability to regenerate lost limbs. In this video Professor Blake Barron from Santa Barbara City College describes the process of sea star regeneration.

While doing a local beach dive I came across this example of what he describes, a two legged sea star with two new limbs starting to bud.

I have two starfish in my saltwater reef tank. It was originally one that I got when it hid in some live rock I purchased. It detached one of it's own legs which grew into another whole starfish. Amazing creatures.

It'd be cool if you did a timelapse photo album/video of a sea star regenerating in a tank or some other closed environment.

I legit just seen this on SpongeBob and looked it up to see if it was true

oyster fishermen: guys we need to cut the starfish limbs off so the oysters are for us!
starfish: that's... how I reproduce...

[thomwheatley]

so wait... it can't regenerate if the central disc is damaged, yet somehow, ripping large numbers of them in half, doubles their numbers, and decimates the clams.

Ciao Clint, grazie per il tuo video!!!

Does orangish-yellow energy shoot out of their limbs when they regenerate?

@Scubaman5000 Just use the madreporite as a register point. First tag one so you know which one to photo .

@PointlessComedy It's leading to research into human limb regeneration. So I'm sure a lot of injured veterans give a damn.

[AmazingSpider-Man]

@Scubaman5000 Actually, all the starfishes do that, not just some; that's the way they reproduce.

[PSNDonutDude]

@Scubaman5000 I've seen it done. In a time lapse.

@thehellsyeah123 there is one in the first HULK movie at the beginning

@TheMarblegirl101 Our school teaches the 4th grade kids the same thing. But I was surprised that our school did not teach us something even more significant, that we humans have a part that regenerates, too: our rib bones. If a doctor cuts out one of your ribs, it will regrow in about 6 months, better than the old one. Surgeons take advantage of this fact and use the ribs to reconstruct the bones of a person's head, after severe injury. I wish our schools would teach us, this too.

the star fish was just like "I don't wanna go"

[skipper]

@theelusivek because star fish are namekians

@Scubaman5000

what about a time lapse of a severed leg growing a new starfish?

[veryepik]

i hope someone dude seeing my commentar on 2020.
*People cut off sea star leg/arm*
Patrick Star: im too lazy to regenerate mah arm

[GorinStudios]

It's been a while since I've read any books on echinoderms but, can the broken limb of the Sea star actually become a new sea star itself? Or am I mistaking its regenerative capabilities for the Planaria?

[Reneator]

@UniteForgetLeftRight its the same problem like with those squid at the japanese coast. With killing them, they will set free Eggs, which will turn into little squidproducing plant like livings, which will produce big number of that squid. So its really like: "you kill one, even more will come back"!

Wait. What happened to the new Wild West format? I really liked it!
