This is a portrait of one of our larger flatworms. The dark brown object
is probably an egg. The large, round thing below the eyespots is the pharynx.
This little flatworm, with its bean-shaped eye-spots, huge mouth and bumpy
skin, probably belongs to the same genus as the larger orange flatworm
above.
This flatworm has no obvious eyespots. The "eyes" in the picture are colorless,
and are probably some sort of sensory pits. Although it is less obvious
with this individual than with others I have seen, this worm probably consists
of two individuals that have not separated from each other after asexual
division. Something seemed to be sticking out of its side on the left,
as shown in the picture.
This individual is probably the same species as the one shown above, but
in this case, the distinctiveness of the two segments was more pronounced.
I could see two sets of sensory pits and two mouths. This is one of our
smaller flatworms.
Here is the companionable flatworm, that never strayed far from the company
of another of its species in the slide. It has no eyespots. The cilia on
this one were particularly easy to see. Some of these get very large.
This beautiful, shaggy, slow-moving flatworm is uncommon
in our sample; we have only seen two of them. I think it's a rhabdocoel,
meaning that it has a simple, undivided sack-like gut. It has attractive
eye-spots.
