Fig. 2

Scanning electron microscope images of the pedal disc and footprint of an individual attached anemone. a A complete footprint with some tissue remaining (t) and mucus secretions (m). b A complete pedal disc with some absent tissue (at) that remained on the substratum. External mucus secretions can be seen on the outside of the animal (m). c A high magnification image of the secreted footprint, which formed a meshwork between the anemone and the substratum. d-e A high magnification image of the pedal disc. Microvilli formed a ‘honeycomb’-like structure on the base which corresponded to the meshwork of the footprint. Scale bars: (a-b) 200 μm (c) 10 μm (d) 20 μm (e) 5 μm
