Alterations were observed in zebrafish embryos exposed to anise myrtle (A,C) and lemon myrtle (B,D) extract for 96 h. Heatmap showing the cumulative morbidity and phenotypic and behavioural alterations (A,B). Hatching delay occurred at higher concentrations for both plant extracts, with other mild alterations. The proportion of total mortality observed each experimental day at different concentrations (C,D). Colours represent the experimental time in hours (24–96 h). Most of the mortality occurred in the first 24 h, though continued exposure to lemon myrtle showed ongoing mortality continuing by subsequent days.
