Maimed salamander

Yesterday my husband C mowed the lawn with a push mower and accidentally maimed a salamander. I guess C mows the lawn so rarely that the salamander didn't run away and its face got sliced by the blades. He put it in a jar with some water, rocks and grass and it hung out with us. It's probably an arboreal salamander "Aneides Lugubris". It was bleeding for a while, then it stopped and moved around a little. I'm not sure how long it'll survive with only one eye and half a mouth, but this morning C will release to a friend's house that has a pond and no grass to mow. Good luck and long life to you, little salamander.
