Fig. 2. (A) Paguristes eremita (pa) in Aporrhais pespelecani shell on top of ascidian Phallusia mammilata (ph) at 13.6 h after anoxia (H₂S 18.3 µmol l^–1). The holothurian Ocnus planci (op) on left. (B) P. eremita (pa) extending from an overturned Murex brandaris shell (mu) at 16.1 h after anoxia (H₂S 36.7 µmol l^–1). Note extended sea anemone (Cereus pedunculatus, ce) at top. (C) Atypical interactions: shell-less hermit crab P. eremita (pa) on top of emerged infaunal sea urchin Schizaster canaliferus (sc) at 35 h after anoxia (H₂S 243.2 µmol l^–1). Note abandoned, overturned M. brandaris (mu) shell on the sediment. Bent-over C. pedunculatus partially extended from tube on right. (D) Dead P. eremita (pa) (curved abdomen visible on bottom) next to its abandoned shell (overturned A. pes-pelecani (ap) at top left). Note typical serpulid-encrusted aperture.
