Table 1 Comparison of mean response times to 2 M glycerol in free-living nematodes

From: Evolution of a polymodal sensory response network

  Species Mean response time (s)
1 Caenorhabditis elegans 1.1
2 Pristionchus pacificus 5.2
3 Cruznema tripartitum 7.4
4 Panagrellus redivivus 8.1
  1. In Caenorhabditis elegans, the animal backs away from the stimulus almost instantaneously within a second. However, avoidance to high osmolarity conditions by more distant species varies. Panagrellus redivivus was the slowest in response time in our assay. Data represented here is the average response time of 40 animals per species tested over multiple days.
