Answer 1

He's actually right, so maybe you should give him a little more credit.
Here are some pictures of starfish that have done this:

Answer 2

Yes
Regeneration
Some species of sea star have the ability to regenerate lost arms and can regrow an entire new arm in time. Most species must have the central part of the body intact to be able to regenerate, but a few can grow an entire starfish from a single ray. Included in this group are the red and blue linkia star. The regeneration of these stars is possible due to the vital organs kept in their arms.

Answer 3

Starfish are well known for their powers of regeneration. A complete new animal can grow from a small fragment such as a arm. In some species (Linckia multifora and Echinaster luzonicus) one of the arms will virtually pull itself away, regenerates and forms a new animal. Autotomy (self amputation) usually is a protective function, losing the body part to escape a predator rather than being eaten. But here it serves as a form of asexual reproduction. In other species of sea stars (Allostichaster polyplax and Coscinasterias calamaria) the body is broken into unequal parts (= fission) then the missing limbs regenerate.

Answer 4

Any piece that includes a portion of the central disc to which the arms are attached can regenerate into a new starfish. Before commercial shellfishermen knew this they used to take starfish that came up in the dredge, chop them into several pieces and toss them back, thinking they were reducing the starfish population, but they were actually increasing it.
.

Answer 5

This is true, as long as the severed arm as a good portion of the center portion of the starfish. The arm would have trouble feeding itself, so it would probably only regenerate in a lab, where someone was feeding it. A more reliable way to clone starfish is to just cut them in half.

Answer 6

Its true ..sea stars make other sea stars from other pieces of them self that have fallen off or been cut off...that is just the way it works this ability also lets the grow new arms

Answer 7

i have sort of lengthy previous throught this, okayy right here it is going. go away HIM female! he's not nicely worth your time. if you're think to have self assurance him and he doesnt have self assurance you thats ****** up. and that i can tell that he's merely putting different women earlier you, once you should be his suitable priority. You both favor to stability it out and take care of eachother like you want to be dealt with, you already know what i recommend. in case you already tried talking to him a million cases and he doesnt pay interest, then obviuously he's not gonna replace. you want to locate someone who provides you with what you deserve. And with him consistently putting you down, he merely needs to make himself experience strong in that way. Dont enable him take care of you want this. I wager you're youthful and extremely fairly, so locate someone who meets your criteria, reason i understand this boyfriend of yours doesnt. he's not the first boyfriend you have ever had, so why follow him and make him your very last :) go away him and tell him that you deserve way extra effective and considering he hasnt made an attempt to regulate then he wont ever be nicely worth it. Who cares in case you damage him, he's consistently hurted you. and in case you do go away him, dont communicate **** or dont be telling all of us that your chuffed or relived or that your sadd. reason then that can provide him extra of an benefit to communicate **** about you. :)

Answer 8

They can only regenerate(regrow) an arm,not a whole new body.

Answer 10
