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.

Octonauts Series 1 13 The Lost Sea Star


Author gary winkler (25 days)
Now there's a right proper payback to the fishermen for their cruelty and
arrogance against the sea stars. I hope they all lost their asses in that
little war against nature. It would be great if all of them lost their
boats for a few years so that the sea might get back some of it's strength
and populations. I would much rather see an ocean full of life than a
bunch of smelly grungy fishermen filling the bars along the coast. They
might even make good fish food!

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.

we should take the seastar's genes and insert it with our genes, maybe we

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.

@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"!

1:02 That is exactly why some parts of China's ocean is over run with Jelly
Fish. When they over fish the sea beds, they also capture Jellies and when
before they toss them overboard, they slice them up and lets all the
Jellies eggs out.

sooo if you cut a starfish in half, will you get 2 starfish as they both
will regenerate?

Did he mentioned that it is possible for a whole starfish to grow from one
of its leg? Like a starfish have 5 legs, rip all 5 and if they all
regenerate you can have 6 starfishes.
