Didinium's Squeeze Bulb Ingestion Technique
Video observation and text by Bruce J Russell
The
Didinium/Paramecium relationship is a classic study in predator prey
relations. Many students of protozoa have seen Didinium spear its
prey using trichites, explosive threads that not only paralyze
the prey, stopping its ciliary beat, but also secure it for engulfment. Didinium
then expands its mouth and swallows the Paramecium. I had filmed
this act several times without clearly showing how the actual engulfment of
the prey (often larger than the predator) is achieved. Staining Paramecium
with congo red allowed clear visualization of Didinium's "squeeze
bulb" ingestion process. This observation is from The Biology of Protists
DVD.

ANSP Algae Image Database website:
http://diatom.acnatsci.org/AlgaeImage/
You can view over 850 light microscope images of diatoms. Over 550 taxa are represented. You can search for images by genus or species, and view thumbnails or full size images. Most images are of diatoms from rivers throughout the United States.
Use the post-a-comment feature to easily add a comment about an image that can be viewed by directly other users. A main purpose of this feature is to promote discussion of taxonomic issues using images in the database as widely accessible examples. -
