Additional Characters The egg contains a single micropylar opening located at the animal pole. It is situated at the bottom of a micropylar cup which lies between the anchor filaments. The diameter of the micropylar funnel is 325 µm. The edges of the honey-comb like structure at the base of the funnel is smooth. The diameter of the mycropylar canal measures 4 µm. Each single anchor filament is between 3.2 and 4.9 mm long and has an anchor-shaped apical end. The number of filaments varies around 50 but is always smaller on the vegetative end (Ref. 51361). On both ends of laid eggs, the filaments are enveloped by a gel-like matrix intertwined with large cytoskeletal biopolymers (keratin-like intermediate filaments) of possible holocrine origin (Ref. 51417).
