- ‘Ascon, sycon, and leucon are levels of complexity that grade one into the other.’
- ‘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.’
