Fluorescent Water Fleas
Water fleas are very fun to watch: they are diverse, abundant, and cute. They also swim very fast with jerky movements. Yet they are also interesting to look at when they are fixed and stained.
In the first picture the flea has lots of babies inside (the blue stuff). The black dots are their eyes. It was really hard to get that those blue things are babies. Without fluorescence they have green eyes and it looks like the giant flea ate lots of algae or something. Only after a lot of image enhancement I could see that clearly. The babies swim in huge numbers in summer water and they look like that:
That's some of the fleas' diversity with fluorescent dyes under UV
Another one with babies inside.
This is definitely not the most successful picture, but the colours look cute.
And the last one looks like some demon from computer games that came straight from hell burning with green fire inside and surrounded with fog
