How do soft bodied brains reproduce?

Like the title says "How do soft bodied brains such as scolys. trachs, and welsys reproduce?"

 

Sexually of course, and some asexual as well.

 

That wasn't exactly a helpful answer. Please go in to detail. Grow new heads, split...what does it look like.

 

Most do it sexually as I stated. Do I really need to go into full detail of that? It's not also Genus dependent as some of the species do it differently.

 

Coral spawning; a future threat?

Open brains and Trach brain will grow new heads basically. As they grow you will see lobes separate and eventually form individuals mouths and polyps. They reproduce similar to branching frogspawns. I believe scolys will eventualy form two mouths, then split, but I'm not sure on that one.
