Fig. 6. Egg attachment system formed on the maternal ovigerous hair and its
stripping after hatching. (A) The egg attachment system formed on an ovigerous
hair. This system consists of a single layer with two sublayers (E1a, E1b).
The fine structure of the attachment sites (enclosed by the open rectangle) is
shown in C. (B) The egg attachment sites arranged at intervals of
130–160 nm on the maternal ovigerous hair. (C) Fine structure of the
attachment of layer E1 to the ovigerous hair (left), and schematic drawing of
this structure (right). A portion of the attachment site is shown by two small
arrows (as). (D) Separation of layer E1 after the embryos have been immersed
in hatch water (left), and its schematic drawing (right). Two small arrows
(as) show a portion of the attachment sites separated from the investment coat
