Fig. 5From: Bacterial symbiont diversity in Arctic seep Oligobrachia siboglinidsPhotomontage of two consecutive transmission electron images of the posterior trophosome of Oligobrachia webbi specimen Vi-005 collected at Nyegga showing bacteria with morphology typical of sulfide oxidizing (SOX) bacteria filling the trophosome. B = SOX-bacteria cut in cross-section, b = SOX-bacteria cut longitudinally, E = trunk epidermis, L = lysosomes containing degraded bacteria, M = myoepithelium, N = nucleus, RER = rough endoplasmic reticulum, W = degraded "onion-peel-like" membrane whirl.
