This is a bryozoan embryo exhibiting its blastopore. These animals are discreet but ubiquitous in oceans and lakes all over the world. What we see is the DNA inside the nucleus of the cells of the embryo. The color gradient indicates if the nuclei are closer (yellow) or further away (purple) from the microscope camera. […]

Bryozoan life cycle
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 :)
Living cyphonautes larva
After the illustration, this is a living cyphonautes larva collected from the plankton.
