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.

Thats fantastic honestly ;) if you try to destroy a sea star, you just end up with anothet one lol.

Author Robert Harley (11 months)
Yes sir, there was a story about a bunch of sailors who hated starfish because they constantly ate all of their fish that they were trying to catch. So each time they caught one they would cut it in half. Lol they ended up tripling their population. Wait I'm listening to the video and I think they might have just told the same story I did.... But whatever.

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?

Author Sarah Red (1 year)
just realised he told the story too x'D

Author Sarah Red (1 year)
More like fragmentation :) Funny story is that fishermen used to cut up starfish and toss them back into the sea to prevent many from eating at the oyster beds. In other words starfish eat at oyster beds and oyster beds are precious to fishermen. Little did they know that each piece regenerated a new starfish. So they actually got far more!! I laughed my brain out at this X'D That's what you get for playing with nature! I hate humans with superior thoughts/act >:(

Can be a very awsome way for medical purpose once they find out wich gen does it and how too use it for humans that have lost there arms or legs or whatever and make it grow back by inserting some sort of abstract based on what causes the sea star too regenerate , unfortunately such a breakthruw probably means allot fo sea stars used for medical science that won't survive all the tons of tests :(
