Contrasting mechanisms of isotopically labelled DOM (a–c) and POM (d–f) incorporation by choanocytes of the LMA species H. caerulea. Correlated NanoSIMS (a, d) and SEM images (b, e) with partial 15N-signal overlay (c, f) show the rapid internalisation of 15N labelled DOM and POM after 0.5 h and 0.25 h, respectively. DOM is incorporated into the apical tip of choanocytes (arrows), while food bacteria are phagocytosed by these filtering cells. The colour scale in a and d represents enrichment relative to natural abundance ratios (in blue, 0.0037). f, food bacteria; v, intracellular vesicle. Scale bars are 1 μm
