A vicious microscopic hunter was caught on camera attacking and devouring another microscopic organism. Who would have thought a battle of microscopic creatures could be so fascinating?
This video features the single celled organism known as Lacrymaria olor, which is a microscopic protist known for preying on other tiny organisms.
The incredible footage was captured by James Weiss, who regularly posts videos of fascinating microbiology finds.
Despite being composed of just a single cell, this organism shows complex behavior. As you can see in the video, Lacrymaria olor can extend itself to surprising lengths.
It’s extendable “neck” has a cell mouth that can inject toxins into prey.

Single-celled Lacrymaria olor hunting. Please be sure to check all the clips in the carousel. . Lacrymaria olor is a vicious hunter I find in ponds, and lakes. Even though it's a single-celled organism, it shows complex behaviors. It can extend its "neck" quite a bit and pokes around. . The tip of the extendable neck has the cell mouth and it is armed with many toxin ejecting structures, when the tip touches something alive, these structures are fired and inject their content into the prey to kill it or snatch a bit of it. . In the first clip you see it eating another single-celled organism, and in the second one snatching half of a big single-celled organism. And in the third clip, one of the Lacrymaria kills and eats a small single-celled organisms. And in the fourth clip you can see the details of its cell. . Lacrymaria olor's name is super beautiful, it means "tears of a swan" because it looks like a swan with its long neck and resembles a teardrop with its body. Me and my fiancée, we decided to name our first daughter as Jane Lacrymaria. Jane after Jane Goodall and Lacrymaria after the Lacrymaria olor. ☺️ . I think my favorite clip of them is the second one, I love seeing that violent clip! . Thank you for reading! Best, James Weiss
