FIGURE 9. Halisarca magellanica. Pocket cells in TEM and SEM. A & B, early stage of mesohyl engulfment through extension of pseudopods (respectively RBINS-POR.12918 & 12921); C, mesohyl within pocket (RBINS-POR. 12921); D, similar view in SEM (RBINS-POR.10753); E & F, later stages with pockets of variable size and number containing mesohyl material and associated bacteria (respectively RBINS-POR. 12920 & 10753); G, ultimate stage with numerous pockets containing bacteria and mesohylar content (RBINS-POR. 12921). (B = bacterium; Gr = electron dense granules of the mesohyl; M = mesohyl; N = nucleus; n = nucleolus; P = pseudopod; Po = pocket).
