Gill filaments of Idas iwaotakii.
(A) TEM view of gill filament of the lateral zone from a specimen of I. iwaotakii collected on wood off Vanuatu. Bacteria (black arrows) are located extracellularly in contact with microvilli. BL: blood lacuna; Lm: basal lamina. (B) Electron micrograph of the extracellular symbionts. Symbiotic bacteria possess a double membrane (white arrow) typical of Gram negative bacteria.
