- 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.
