It is moving under its on power. It has no flagella. As far as I know, no particular explanation of how it moves has been experimentally verified. One commonly-proposed explanation is that it actively pumps water through small pores in its silicon dioxide shells [called "valves"].
Very cool!!! I Think that is a Gyrosigma balticum because of the rafe insertion..I have found this diatom at many brackish water of south brazilians bay...at low densities too (sorry my english, it is very easy)
Yes, I think it is a species of Gyrosigma. I wish I could nail it down to a species because I have found it in almost every San Francisco Bay salt marsh pond. It is a minority micro-community member, but occurs over a wide range of salinities.
To be exact, diatoms are algae and algae belong to the Kingdon Protoctista, not the Kingdom Plantae [view of Margulis and others, see Wikipedia]. The generic word "plants" is handy for critters that have chloroplasts and use sunlight to fix carbon dioxide.

how is it moving just with the currents? or by branching out? or by flagella moving so fast we cant see?

It may also be Pleurosigma. Email me if you are interested in finding out exactly.

sorry, but as far as I remember Algae are no plants and diatoms belong to the Protista

See my web site for details on lights for the Swift Field Microscope. I tried to put it here, but exceeded the allowed number of words.
