Shark teeth tell us a lot In our substack book Born Predators, Kinney looks closely at wounds “A Bull shark has cutting teeth in the upper jaw for slicing and stiletto points in the lower for grasping. I don’t see that.”
“So, not a Bull shark,” the coroner offered
“No,” Kinney said. "Something else"

#jaws50th 50 years after Jaws we know a lot more about sharks. Big white sharks are usually female. They get pregnant and give birth to young in the summer looking for a warm shallow cove Was that the Jaws shark? In our book Born Predators Hennessey the shark is doing just that but gets into trouble

#Jaws50 Today we know a lot more about sharks. Can they be wildlife not monsters? In our new novel Born Predators the shark biologist sets out to prove the shark Hennessey didn’t attack anyone – but it turns out that people are more complex than sharks.

Suppose you were the shark? TODAY! The 50th anniversary of JAWS, which defined the movie thriller by having a monster in the water. If you were the shark and had to live with that label for 50 years, how would you tell the story differently?

5 DAYS TO THE 50TH ANNIVERSARY OF JAWS: THINGS WE KNOW NOW:
Sharks continuously grow their teeth—a new set every 7–10 days—and discard the old ones like dull razors. Over the course of a life time sharks can lose 10,000’s of teeth.

Innovations are key to the success of new groups—in this case the first invention of teeth for a global ocean predator. stephenpalumbi.substack.com/p/born-preda...
