Another of my "Numbered Days" series of endangered creatures.
These cute little fellers are found only in the San Francisco Bay area. They are very unusual in that they drink salt water and swim very well, floating on the tide looking for pickleweed plants to munch upon. Their days are numbered because housing developments continually drain or dyke the marshlands near the bay, eliminating their habitat. I'm not a huge fan of mice, but I'm rooting for them!
