These guys are common in my pond-water aquarium.
Although they almost certainly occur on all surfaces they are most readily seen cruising on the lower surface of the surface film.
This is a series of 6 focus levels from the ventral surface (top left of 1st plate) to dorsal surface (2nd plate, last image bottom right) showing:
#1-#3:the ventral 5 transverse cirri, these tendril-like structures are composed of fused cilia and are used for walking on surfaces.
#2-#3: well-developed AZM (adoral zone of membranelles)
#3-#6: lots of food vacuoles.

Quote – Holmes on ‘Entomology’
” I suppose you are an entomologist ? “
” Not quite so ambitious as that, sir. I should like to put my eyes on the individual entitled to that name.
No man can be truly called an entomologist,
sir; the subject is too vast for any single human intelligence to grasp.”
