Figure 5. PKD2-1 is required for predator avoidance and escape.

(A) Adult Centropages typicus female approaching a nectochaete Platynereis larva (arrowhead). (B) Predation on wildtype (+/+) and PKD2-1^mut/mut larvae by C. typicus. Paired values are joined by blue, grey or red lines if predation rates were higher, equal or lower in mutant than in wildtype larvae, respectively; data from 42 trials with 12 batches. One-sided exact Wilcoxon-Pratt signed rank test, P $=$ 5.2e-10.
