...), well known as an adult chemical defense, stimulates larval escape to refuges. Although they are cannibals,adult newts feed preferentially on worms ( Eisenia rosea ) over conspecific young. Hence, larval avoidance reactions to TTX are suppressed in the presence of odor from these alternative prey...

... suppressed cannibal-avoidance and failed to evoke search reactions in larvae. For a common set of arginine analogs, the magnitudes of adult attraction and larval suppression were not positively correlated. Suppression of cannibal-avoidance behavior in larvae was unaffected by most structural modifications...
