That's odd; your description of the brain-coral-looking bryozoans seems to
differ from the ones I have seen. Mine look light grayish in color and not
clear. Their overall shape was more hemispherical than spherical. I haven't
seen any robust specimens growing in the sun, but then again this is a
temporary pool with lots of shade trees along its side. There are unshaded
areas, but I didn't really see any bryozoans in those areas. I didn't notice
any polyps, but given the fact that the specimen was somewhat ruined by
handling it could've still had some and I just didn't see any. The bryozoans
that were exposed to sunlight had a greenish tinge her and there, while still
retaining their overall light gray coloring. I'm thinking that either we have
different species that have a basically similar appearance, or they are the
same species growing differently under different conditions.
