  I genuinely don’t know the answer to this question. If anyone does, tell me so I can tell SavageOnFleek!

  I had to ask my girlfriend this question, she is in veterinary school right now. I originally thought it was zero! However, she said they only have bones in their teeth (made of calcium phosphate), the rest of their body is made of cartilage.

  I don’t know!
  
  I do know that we don’t actually know how sex is determined in sharks. Curious, huh.
