DIATOMS, ROTIFERS and SOMEONE UNIQUE
The water drop sample from the paddy field further showed moving diatoms and rotifers.
One particular organism puzzled me. At first, from its bifurcated tail, I thought it was a rotifer. But on better focusing, I observed its cilia.
Was it a ciliate? It seemed too big for a ciliate. YouTube and Google explorations indicated that this was neither a rotifer nor a ciliate, but an organism called Chaetonotus, belonging to the Phylum Gastrotricha.
Chaetonotus was an incredibly fast microbe and I struggled over an entire day to capture its movements in my videos. At the end of the day, when I finally recorded this video, this poor Chaetonotus must have been exhausted, as its movements had become very slow. I later learnt that the average life span of a gastrotrich is only around 3-21 days.
Look out for the next post!
