Re: Lacrymaria - Dance of Love - Conjugation
convinced myself that a longitudinal division might end at the "mouth" True longitudinal division is pretty rare, in ciliates. Peritrichs do it that way (but that is probably a very derived kind of transverse fission, in which the whole organism is rotated by 90 degrees). is this showing the early ...

Re: Lacrymaria dividing
Lovely! :) The video shows cells in conjugation...i.e. having sex, not dividing. :) Division in Lacrymaria (as in most ciliates) is transverse, across the middle of the cell. In division, both the mother and daughter cells would be pointing in the same direction, whereas in conjugation they face on...

Re: Marine Diatom from the Gulf of Thailand, Koh Kut
Might that be a girdle view of a cenrtric diatom? You're fast approaching that point where you spend untold hours trying to identify these! It very well could be a girdle view. I shot many diatoms on an angle where it was clear that there were two centric halves of a diatom connected to each other ...

Suctorian tentacle movement
A closeup look at Suctorian tentacle movement. Suctorians have a spiral structure around their tentacles that acts like an accordian, moving the tentacles in and out.
Playback at 8x speed to better show this movement, which is very slow in real time.

Huge bloom of Euglena sanguinea, imaged at 10x darkfield, 20x, and 40x oil.
Freshwater sample from Lumpini park, Bangkok, Thailand.
The red color is due to the presence of the carotenoid astaxanthin, an antioxidant. Astaxanthin is responsible for the pink-red color of salmon.

Re: Rotifer hatching
Sure. In the first shot you see an egg attached to a rotifer. The baby rotifer has begun breaking out of it's egg. Each successive shot shoes the baby rotifer breaking further out of it's egg., until at the end it has broken free and immediately begins feeding.
