P. pacificus /amphid opening near mouth/DiI stained amphid neurons Nematodes are ideal candidates for the study of development and behavior in the context of their ecology because they are ubiquitous, small organisms that occupy most of the Earth’s known ecological niches: soil, animals, and plants.

Pristionchus pacificus is a species of free-living nematodes (roundworms) in the family Diplogastridae. The species has been established as a satellite model organism to Caenorhabditis elegans , with which it shared a common ancestor 200-300 million years ago. P. pacificus may refer to: Pristionchus pacificus, a free-living nematode Polistes pacificus, a neotropical paper wasp Palaemon pacificus, a species of shrimp Parazen pacificus, an Atlantic zeiform fish Paraconcavus pacificus, an acorn barnacle Philanthus pacificus, another species of New World wasp Pristionchus pacificus is part of the diplogastrids, a clade nested within the rhabditid group where C. elegans belongs. Like C. elegans, P. pacificus reproduces with selfing protandrous XX hermaphrodites and facultative X0 males. It is found on several continents, associated with beetles.

Forward and reverse genetics tools have been developed to allow detailed comparisons to the rhabditid nematode 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 Caeno the eurystomatous morph of Pristionchus nematodes (shown here P. pacificus) can capture and prey on other nematodes (prey here C. elegans).

P. pacificus propagates through four juvenile stages, called J1 to J4. In contrast to C. elegans, the J1 to J2 molt is embryonic and only the J2 stage hatches from the egg. Dauer formation occurs as alternative J3 stage, as in C. elegans. The direct life cycle takes approximately 4 days at 20°C. P. pacificus young adults: Exposed to Serratia marcescens versus exposed to E. coli OP50 : 4 hours.

Under well-fed conditions, ascaroside biosynthesis proceeds exclusively via Ppa-daf-22.1 In contrast, starvation conditions induce Ppa-daf-22.2 activity, resulting in the production of a specific subset of ascarosides. P. pacificus dauers are associated with many scarab beetles, such as Exomala orientalis (left), and Oryctes borbonicus (right). After the natural death of its host, P. pacificus exits the dauer stage, resumes its development, and starts feeding on microbes that grow on the beetle carcass; (c) P. pacificus is equipped with versatile teeth‐like Notably, only 128 out of 1288 operons in C. elegans are conserved in P. pacificus. However, analysis of gene-expression profiles identified conserved functions such as an enrichment of germline-expressed genes and higher expression levels of operonic genes during recovery from dauer arrest in both species.
