They have snails that breathe underwater. They put them in salt water aquariums and they
crawl around inside and clean up the glass. They work pretty good. :-) Now, how could you keep
them on those under water windows?


The designer calls them "Acrylic View Ports".

They might like the hull better.
That makes me think of something. One of those rude *down under* people made fun of me
for saying "windows in the hull". Are those windows in that habitat hull? If they ain't windows
what are they?
