Trichodina

Post by bernhardinho »

Hi folks,

found some nice hydras the other day. Many of them had lots of the ciliate Trichodina pediculus on them, which is quite typical. Here are some shots

Hi Bernhard, nice captures of this famous peritrich, the "Polypenlaus". I found them once on a Craspedacusta sowerbyi, a fresh water medusa and Trichodina species are reported to be a pest in fish.

On the first picture one can recognize the basal system of organelles for adhesion and locomotion. In full view from the undersurface these structures always somehow remind me of the shearing wheels of my friend´s electric Philips shaver. :D
Thanks for sharing.

Best wishes,
Betty

So, this creature is parasitic on the hydra? Does it bore into the host with the radial structure and suck juices?

Hi Doug,

not that I knew of! According to Kahl it does not harm the host, but feeds on bacteria. The interesting thing is, that it doesn't get "shot"by the hydras penetrants (whereas copepodes and rotifers do stand much inferior chances!)

Hi Bernhard,
Another interesting critter that I have occasionally looked for but not found yet. And here you're getting them sitting 5 in a row! :wink:
Great to see the pictures.
