Movements of young tardigrades
within their eggs.
At the end of the egg development the eggs become very clear and translucid.
In the middle egg you will see the pair of bent stilettos by means of which
the grown-up water bears will pierce moss cells in order to prepare their
moss muesli. The thin line between the two stilettos is the buccal tube
through which the almost liquid moss muesli enters into the stomach.
The globular chewing stomach has solid structures (small grains in the clip
to the left) which serve to crunch solid particles, similar in function to
human teeth. Image width about 200 µm.
