Thank you for the feedback. On the first image I am trying to identify the plants on the midground, in front of the ludwigia and behind the hairgrass (which, by the way, is Eleocharis parvula). I believe trout gave a really nice shot at suggesting the ozelot, but I am not a plant expert either.
On the second picture, I am trying to figure out the kind of plant on the background, with long, flat leaves, behind the grass.
On the third one, I am trying to identify the spiral leaves on the foreground, in front of the red tiger lotus nod. The base/roots of the plant is on the lower left quadrant of the image.
Sorry for being so vague. I was trying to have the images available as fast as possible.
