I'm guessing the curly end is the head.

Trichuris trichiura or "whipworm" I think. The eggs look like lemons and make me super thirsty for lemonade everytime. I think the narrow curly end is the mouth/esophageal end because I vaguely recall it is the opposite of what I would immediately guess. Sweet case!

trichuris trichura or more accurately tricocephalus

Female Trichuris, the posterior is thickened, so the skinny part is the head. The Posterior is not curled, so I am guessing female...Lee
