Order Breviatida
Class Breviatea
Gender Breviata
"Breviatea" are flagellated amoeboid protists.
As we can see in the video was found in marine putrid water without oxygen.
Its body measures about 10um long.
As you can see, it have two flagella, one anterior and one porterior.
In its posterior flagellum it presents "acronematic" (finest area at the end of it)
And fine filopodia born of her body.
I thank infinitely to Alastair Simpson and Yana Eglit their invaluable help in identifying this organism

Weird beast! You certainly have a knack for finding some strange ones. Looks like the place to search is water with rotting seaweed.

Hi David.
In reality they are organisms that live in the absence of oxygen.
and as you indicate, this is one of the few ways of find anaerobic organisms.
Others, like spirilli (see my others post), proliferate before running out of oxygen.
I also observed many Euplotes sp living in these saltwater environments without oxygen.
The most unpleasant stage is when proliferate spirilli and others sulfur bacterium, I guess because the sulfur decomposition.
Some days after everything dies.

That's a really interesting find, Carlos!

Are you going to send it to Simpson's lab at Halifax? Yana has a way with anaerobes.

I wrote to her to teach me how to cultivate and take samples
but these organisms live a few days and I do not know how to cultivate
