From: Leachate effects of pelagic Sargassum spp. on larval swimming behavior of the coral Acropora palmata
The four trajectometry indexes used to evaluate spiral movement in Acropora palmata larvae exposed to five treatments (control, stain, and 25%, 50% and 100% leachates). (A) Percentage of larvae with spiral displacement. (B) Mean spiral displacement-length per larva. (C) Mean spiral displacement-time per larva. (D) Mean spiral displacement-speed per larva. Letters above the bars indicate significant differences according to post hoc analyses; ns = not significant. Error bars represent standard error.
