Alarm signal tadpoles

Hypothesis 4 An alarm signal exists which reduces time to metamorphosis and mass at metamorphosis of cane toad tadpoles. 

Latent alarm signals seem to be present in vertebrates, especially in tadpoles of fix)gs, and the existence of such signals may explain some basic evolution questions in e relationships between predators and prey. The presumable inactive compounds in question may be activated by the bacterial flora within the gut of predators, explaining why taxonomically different predators may release diverse responses within one single prey species. Knowing the exact source of the alarm signals will be of utmost importance for future work within predator-prey interactions.
