Student Project Figures Figure 3 Figure 3. The mouthparts of Liomera rubra are seen circled in blue. These mouthparts include the maxillipeds, which are seen protruding slightly near the bottom of the circled area. These appendages are specially adapted for feeding, and allow the organism to collect food off its coral host. The maxillipeds are retracted in the photo because the organism is not feeding.  Figure 2 Figure 3 Figure 4
