Ahh, this crazy weather/ changing 'new normal' weather...by 1/26/24..all snow on ground melted..ice in the stream-pond meso cosum mostly melted. This worries me.
The area streams were all swollen with melt water..my good doggie sensibly did not enter the rapid angry stream flow.

Collotheca sp. of rotifer, in secreted gelatinous tube , a free living 'sessile rotifer' in our freshwaters. The long spines are moved to entrap small metazoan prey..push prey into that huge funnel mouth openning..that funnel mouth snaps shut.
This rotifer has a poorly ciliated corona.
