I have a kid’s microscope and decided to use it because I have some brown algae on the glass-not much, but still. So I decided to take a look for fun. Its obviously not the best quality, but does it look like some diatoms?
Scientists estimate there are tens of thousands, maybe even millions of different species of Diatoms. It hard to say, but if I were a gambling man, I would bet that some of the microalgae on the slide are Diatoms.
