Starfish are bizarre. They start as a bilaterally symmetrical larva, then grow a stalk that attaches to the sea bed. They grow, then rearrange themselves into a pentaradially symmetrical form.

Plus they can regenerate from a severed limb! Creepy, but very interesting too.
- polishdude20 3y agoJellyfish are really weird too. They produce like spores that then go down to the surface and create factories that create little baby jellyfish.
- Obscurity4340 3y agoWhat do you mean by "down to the surface"?
- polishdude20 3y agoI mean the sea floor haha
- Obscurity4340 3y agoWhy do you have to be so affable about it ;)?
- permo-w 3y agoif they can regenerate from a severed limb does this mean they can be cloned into 5?
- simcop2387 3y agoMy understanding is that they can regrow from all the severed parts if done correctly, so 6 at a time. Arms and central core.
- generic92034 3y agoHow would a separated arm part nourish itself?
- bloopernova 3y agoIn the Wikipedia article, it states they live off stored nutrients until they can grow a mouth and stomach. So very, very weird!
- sp332 3y agoIt depends on the species at least https://en.m.wikipedia.org/wiki/Starfish_regeneration#Degrees_of_regeneration https://en.m.wikipedia.org/wiki/Starfish_regeneration#Degree...
- oboes 3y agoAn even more bizarre animal is Dendrogaster, a starfish parasite. Believe it or not, but it's a crustacean. It grows inside a starfish's body cavity until filling it completely, which explains the strange shape of the parasite. https://www.australiangeographic.com.au/blogs/creatura-blog/2023/03/the-dendrogaster-parasite-is-the-stuff-of-nightmares/ https://www.australiangeographic.com.au/blogs/creatura-blog/...
- bitwize 3y agoOh, geez, that reminds me of the Mimics from All You Need Is Kill (the basis of Edge of Tomorrow. In the novel, the Mimics are not the alien invaders themselves, but rather nanomachine colonies sent by the actual aliens that infest and control the bodies of starfish, adapting them to combat use.
- bafe 3y agoIf you are interested in parasitic crustaceans,you could have a fun time reading about sacculina and the mysterious Y larva
- fortran77 3y agoIt is really creepy because they often regenerate funny. See reddit https://www.reddit.com/r/deformedstarfish https://www.reddit.com/r/deformedstarfish
