The woman mortal lays her eggs within the neckband together with spreads it evenly approximately the structure. Influenza A virus subtype H5N1 instant layer of sand together with mucus protects the thousands of eggs contained within the sand collar. When finished , the snail leaves the sand neckband past times earthworks into the sand together with moving away from underneath it.
