P. pacificus eats C. elegans!

Описание: 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 interested in how this behavioral complexity can be encoded in neural circuits without the addition of new neurons. See http://www.acrobeles.wordpress.com for more.
