The photos include the following:

• A beautiful Rotifer - only wish I could get video - they are so active, and you just want them to get their food, internal organs pumping

• Fungal growth scraping from black mould (Stachybotrys chartarum) in the grit of the tiles in the shower - see Stachybotrys chartarum on Wikipedia for further information on this organism. Except the non-blue image, the sample has been stained with Methylene Blue, which is responsible for the stunning blue colour.
