The BEST footage of bryozoan life cycle on the internet. Meet the coronate larva of Bugula neritina. Wow!
The name cyphonautes was created by Ehrenberg (1834), who first saw the tiny creature on Nov. 25, 1832 (Hyman 1959).
Elegant schematic drawing of a bryozoan cyphonautes larva from 1907 https://www.biodiversitylibrary.org/page/10304879#page/324/mode/1up Thanks to @BioDivLibrary. Made me smile :)
After the illustration, this is a living cyphonautes larva collected from the plankton.
