Leptophrys vorax
Leptophrys spec., 95 µm, characteristic locomotion
Leptophrys vorax
Here the cell moves both to the right and to the left, getting longer and longer, but eventually the right side dominates and the opposite side is pulled out.
Leptophrys vorax
Expanded form, body about 160 µm; note the anchor points where hyaloplasm is attached to the slide.
Leptophrys vorax
Small specimen; the white arrow shows the direction of locomotion, the black arrow points to an anchor point.
Leptophrys vorax
The same specimen as above. The arrow shows the direction of locomotion.
Leptophrys vorax
Note the small granules at the edge of hyaloplasm and body.
Leptophrys vorax
Detail: cytoplasmic granules, possibly a kind of membranosomes as in Vampyrella.
