Known Subspecies/Hybrids

[Jntg4]

Are there any known subspecies or hybrids of shark species?

What is the status of Sphyrna tiburo tiburo and S. t. vespertina? Is the Cortez Horn Shark a hybrid?

Hybrids don't become speices... they're just a mix.
I've never heard talk of a sub species of bonnethead.

I know they don't become species...

but I heard that the Cortez Horn Shark may be a naturally occurring hybrid between 2 species of Heterodontus (forget which 2)... so I was asking...
