A Two-Headed Ciliate and Other Adorable, Dead, and Extinct Things

The video explores unexpected discoveries in microscopy, starting with sea squirts and their symbiotic algae. It then examines ciliates, including a rare two-headed variant. An accidental fish capture reveals the iridescence of its eye, highlighting differences in light reflection. Finally, the video discusses mammoth hair from Siberia, seeking ancient ciliates, and reflects on climate change's role in revealing these ancient samples.
