Stentor in a lorica.

#1 Post by D0c » Tue Feb 23, 2021 4:24 pm

Yesterday while searching through a specimen jar of pond water I came across a few stentors within loricas. The macronucleaus appears to be long and worm like and in one video stretches nearly as far as the foot so I'm thinking Stentor roeselii.

A lorica is a gelatinous tube that the stentor builds from detritus and excreted matter. Not all stentors make these and even if one does, it can vacate it at anytime.

Nice! Looks like he's been working on that tube for a while. :D

Thanks :D

I wonder how long it takes to build one, and is there a video anywhere on the web that shows a stentor building one, like a timelapse.

Lorica is the name of the armor worn by soldiers in medieval times. Interesting.
