Samuel Gruber does not need any introductions - he is pretty much synonymous with sharks. And while the Doc has been researching sharks for over 40 years, he has also developed a very deep relationship with these animals. I think the sequence above sums up his love for sharks.
The photos were taken by Tristan Guttridge. Says the Doc: "This mama gave birth to 14 pups, all filmed by National Geo. We took each one to the mangroves, measured, weighted and released after taking a small fin clip for DNA."
I believe it was just Samuel's birthday - two days ago - HAPPY BIRTHDAY.
