Embryonic development of C. elegans
Development of a C. elegans embryo from the first cell division until hatching.
The movie was acquired at a temperature of 20C using DIC optics.

Asymmetric Cell Division in Early Embryo
C. elegans embryo carrying GFP-PH and Histone- mCherry imaged from single-cell stage post-fertilization. The migration of female pronucleus towards the male pronucleus is followed by nuclear envelope breakdown, segregation of chromosomes and asymmetric cell division. These early asymmetric division defines the three principal body plane axes namely anterior-posterior, dorso-ventral, and left-right. The first asymmetric division defines the anterior- posterior axis with Anterior to the left of the frame and posterior to the right. At the four cell stage, the bottom of the frame is destined to be the dorsal side while the top part becomes the ventral side of the organism. (Courtesy of Ronen lab.)
Mating Behavior
The movie below shows mating behavior of C. elegans. This is their most complex behavior, programmed in a handful neurons in a male C. Elegans.
P. pacificus eats C. elegans
Pristionchus pacificus is a nematode that can take advantage of many different food sources. In this video, it can be seen utilizing the model organism Caenorhabditis elegans as prey. A small tooth in the mouth opening punctures the cuticle of its prey, then it sucks in the contents. This predatory feeding behavior represents a more complex palette of behavior than C. elegans, but the nervous systems are composed of the same neurons. I am inter
