1、Tadpoles adjust their behavior according t the presence of fish and group size, reducing activity. Scholars examined the effects of predator cues and group size of a specific kind of tadpoles. They were less active and used the vegetated side of the exp. Group size had no effect. Fish have greater impact than group size
2、Individual in larger groups to perceive lower predation risk and to engage in riskier behavior compared to individual that are alone or in smaller groups. Such pattern also in mammals,fish.
3、Tadpoles adjust activity or behavior in response to number of conspecifics in a group. They use group size to assess predation risk. They are positively correlated.
4、Studied another type of tadpoles of predator cues and group size, prove the previous finding.
