This fellow/lady is a round worm or, Caenorhabditis elgans.
A small town high school, close to us, has been awarded a $7000 grant to conduct scientific studies of the worm. Real science, high school kids, worms - what could be better?
I loved biology in high school and loved it in college. One of many majors I wish I could have crammed in. We ran our own unofficial biology lab in the house where we housed and fed any number of critters the neighborhood tribe brought to us. Favorite memory neighbor boy calling to me, while I was making dinner, 'Mrs. P! Mrs. P! Look - it is eating the guts out!! You gotta see this!'
