Dinos - What is It? How do I know if I have it?

[Reef GE]

I see LOTS of conversations about Dinos on this forum, but have no idea what they are or how to spot them.

Can anyone post a pic or video on this thread to help me identify them (if I have them)?

I have lots of tiny white spots on my glass and sump, how do I know if these are Dinos?
