It can be pretty cool to see this, since it’s sharks. Like, woah. (No, just me?)

Some sharks have been seen with courtship rituals and some sort of “dance,” while others species just… well, get to the point.
As you can see from the videos above, most do it while they swim parallel to each other, sometimes both sharks pointing down to the ground with their snouts. It is here that the male then inserts a clasper (note: they usually only have one in at a time, though it was once reported that a Tope shark had both in, together) into the female’s oviduct to deposit sperm. Claspers can seen below.
How does one do that, you may ask? Well, the claspers aren’t just sausage-looking all the time. The tip actually unfolds and is this… pointy, spur thing.
Scientific descriptive words right there, my friends. The truth is, I can’t even explain it, just look at it.
Remember how this happened to me while volunteering with FSU this summer? Yeah, you can bet your bottom’s dollar that I let out a, “What in God’s name is that?! What’s wrong with it?!”
And that day, Melissa learned sharks are always teaching her something. Always.
Unlike the famous (or infamous) guy on Reddit who DOES have two penises, sharks don’t technically have penises.
They have claspers.
And what claspers do is deposit sperm into the cloaca. The reason that they have two claspers is because they have two pelvic fins. The claspers are an extension of those pelvic fins! See the difference between the male and female here:
Oviparity: sharks lay eggs.
Viviparity: developing pups have a placental link to momma shark and then the pups are born live.
Ovoviviparity: eggs develop inside momma shark, hatch inside the oviduct and then pups are born fully functional.
There is no parental care given by shark mom or dad (in fact, dad isn't even present) once the baby is born. In fact, most swim far away from momma shark because she may eat them as a snack! (Lets not even talk about intra-uterine cannibalism.)
Welcome to the "love"-world of sharks, mates!
Have a fantastic Valentine’s Day and lay off the love nips, alright?
