Interesting that there are blue birds >and flowers but not blue animals; where is a biologist when we need one! A blue animal would stand out too vividly and be a target in most areas. The birds- having few predators- have again and again picked up on sexual selection and run wild with it. Thus the birds end up with fantastic and useless (except to attract mates) plumages. Flowers, again, want to attract for sexual reasons, but bees mainly see in different wavelengths than we humans- flowers would be even more spectacular if we could see as a bee. However, I would bet money there are blue animals besides those in the ocean, such as some snails, some lizards, and some amphibeans.
