Table 2.

Comparison of the fast-start response kinematics of three juvenile damselfishes that have been kept in seawater that has passed over live-healthy coral or dead-degraded coral (Habitat), and then either exposed to either clean seawater or conspecific alarm odours (Cues) within the burst arena just prior to being startled.

Damselfish belong to the genus Pomacentrus. Results show the outcome of two-factor ANOVA’s on three kinematic variables: response distance (m), speed (m/s) and maximum speed (m/s). Bold values are significant at 0.05.
