Stills from time-lapse light microscope movies displaying the representative processes that characterise the contact response phase, i.e., tissue enlargement, mucus release, wound cleaning (0–5 days). (a) Wounds (Wd) formed by abrasion are cleaned by mesenterial filaments (MF) as the surrounding immunocompromised tissues become enlarged (Enl). (b, c) Mesenterial filament deployment is increased external to the body cavity as the compromised tissues become further enlarged (2–3 days). (d) Mucus (Mu) secretions that have formed on the substrate surface surrounding the compromised tissues change colour over time—from transparent to white or brown. (e) A plot showing the relative density of the mesenterial filaments activity inside and outside the body cavity on each day the still (a,b,c,d) was captured. Wound; Wd, Enlarged tissues; Enl, mesenterial filaments; MF, mucus layer; Mu.
