Video: Pygmy seahorses are super tiny creatures that have the awesome ability to camouflage. They attach themselves to colourful corals and blend in so seamlessly that I have a hard time picking them out.

Economic downturn be damned, this pair of spliff-shaped buildings are determined to rise high on the Dubai horizon.
