Acanthaster move selectively to Marine Protected Areas (MPAs).

Movement directions of initial (solid dots) and final (open dots) Acanthaster relocations from release points at MPA/non-MPA borders on each side of the MPA at each of the three villages. Arrows represent the resultant vector (R) for initial (black) and final (gray) relocations. * and * indicate a significant difference between Acanthaster movement towards MPAs (white region) rather than fished areas (shaded region) (Modified Hodges-Ajne test, p < 0.050).
