Hello again 
I read about egg-laying in cuttlefish Sepia officinalis...
Sepia eggs are covered with a primary envelope by the oviductal glands -> eggs are released into the mantle cavity -> they get a second envelope by the nidamental + accessory nidamental gland (nidamental jelly with bacterias) and leave the mantle through the funnel. The nidamental jelly is soft at the beginning and later polimerizes after contact with seawater...
My question is: If the nidamental jelly is released into the mantle cavity to surround the eggs, how do females keep their gills clean? I would expect the nidamental jelly to pollute the branchial filaments and thus disturbing ventilation... :?
Does anybody know how females deal with that or am I missing something and thinking in a wrong direction?
Thankx and best regards,
TK
