THESE slimy creatures may look like aliens from another planet but they are actually the life teeming inside a SINGLE drop of pond water. The colourful organisms were captured using high-definition microscopy. The 'pond safari' pictures show everything from a paramecium moving through bacteria to a hydra 'defecating'. They were filmed by Peter Matulavich from Ohio, USA.
