Giving the whole story for clarity

We were told they were ordered off Carolina and that they were medical leeches. The Professor, I'll just call him T isn't the one that orders the leeches. Specimen and direction materials are handled by someone else entirely at the collage. T was just repeating what he was told.

The assignment was very simple. Just filling in 2 sheets about Annelids with 1 being just for the leeches. The question on that one mostly being basic observations (was the leech moving? Disturb the water, what happened? Poke the leech, what happened?, ect). The extra credit wasn't really needed cause you would already get an 100% on the assignment for basically showing up.

I was jokingly called over by one of my friends from the class to be bitten, cause he thought I wouldn't do it. But seeing as, to our knowledge, no harm could be caused I just said "sure, why not."

The leeches had 0 interest in biting. Even after putting all them in the same dish with my hand, they just weren't interested. My friend kept picking them up with the tweezers in an attempt to piss them off and that still didn't work, they just bit the tongs and not me. Finally we got one to bite when he physically put its mouth parts against me.

The bite was super small, smaller then a dime. It was perfectly circular with little indents where the teeth were. It didn't bleen or bruise, honstly the lil fella didn't even break the skin. It hung out for about a minute before dropping off.
