- Sycons are quick enough at regenerating to cope, I have a few different species on the way too that would probably be suitable, I might try and culture some.
- In the tide-pools all four calcareous sponges occur in quantity, and under heavy masses of weed both the Sycons are equally abundant.
Derivatives
syconoid

- It is the only class with asconoid and syconoid construction, and has sponges with leuconoid construction as well.
- Glass sponges most closely resemble syconoid sponges, but they differ too much internally from other sponges to be considered truly syconoid.
