I'm sure that's correct. Another thing about Hys is that they will literally transform to a dark green color when they're soaking wet - and you don't need to snap a photo to see it . It's far less attractive than the blueness of their dry state, IMO. But they always dry out enough to revert back to their cobalt blue brilliance in a short while.
Yes, certaainly. There's nothing wrong with supporting organizations such as zoos!
