Fig. 6. Scanning electron micrographs of cross sections of Busycon
canaliculatum egg capsules. (A,C) An extract-induced `immature capsule'
at low magnification (B; scale bar, 100 µm) and high magnification (C;
scale bar, 20 µm). (B,D) A native capsule at low magnification (B; scale
bar, 100 µm) and high magnification (D; scale bar, 20 µm). Common to
both is a structured layer of sheets that upon closer examination yield
distinct ordered fibrous content.
