This is the 2nd post about Pedipes ovalis, a tiny (~3 mm long) semi-terrestrial snail that lives at the edge of the sea. The 1st post was here.
Here is a close-up of the front of the head of Pedipes.
It almost looks like the snail has a face, doesn't it? The black eyes at the bases of the tentacles are indeed eyes; but the "nose", the vertical, grayish patch, I believe, is the radula and the "mouth" below it is the jaw. Both the radula and the jaw are within the head, but they are visible because the tissues are transparent.
More will follow.
