Lacrymaria olor - aka Swan Neck Animal

#1 Post by ImperatorRex » Sat Jun 08, 2019 7:54 am

The protist Lacrymaria olor ("Swan neck tear") is notable for its ability to extend the anterior end of the cell up to 7 times its body length, and manipulate in many directions — even around obstacles — in order to capture its food.

Amazing find and a great video!

When using your inverted scope for live specimens what sort of sample containers do you use?

Pls. have look here: viewtopic.php?f=24&t=5930#p53567

The micro-aquarium with 1mm thickness are very convenient. Recently I also have bought some cheap plastic petr-dishes where I drilled a 40mm dia hole & fix were I fix a 50mm round coverglas with vaseline.
