Today in bio lab we dissected dogfish shark.
My team had a male--we could tell because of the claspers surrounding his cloaca.
After eviscerating the digestive tract, we moved on to the reproductive system. I was following the path of sperm from the testes, through the seminal vesicles down to the seminiferous tubules near the cloaca. Trying to identify where the sperm are ejected from the cloaca, I gave it a little pressure and---squirt.
Like a volcanic eruption, preserved white semen ejected from a hole under the claspers of the cloaca.
Hot, huh?
At least I can please sharks! :)
