Interesting Facts

    • Leopard sharks are known to school in large numbers, often with other sharks, including the gray smoothhound shark, brown smoothhound, and Pacific spiny dogfish.
    • Leopard sharks can live up to 24 years in the wild, and 28 years in zoos and aquariums. 
    • Leopard sharks give birth to live young! Like most fish, baby leopard sharks are hatched in an egg, but the mother keeps the egg inside of her until the pups are ready to be born. A female can lay 8-33 pups at a time! 
    • Leopard sharks swarm to the waters right near this map, the Matlahuayl State Marine Reserve, in massive numbers every summer. Andy Nosal discovered during his PhD at Scripps Institution of Oceanography that the majority of those leopard sharks were pregnant females, coming to enjoy the warm, calm, protected waters of La Jolla Shores.

Want to see leopard sharks in person but it’s the wrong time of year to see them off the coast? Come see them live at Birch Aquarium or at the San Diego Zoo

Snorkel with a Birch Aquarium naturalist here on a Shark Snorkel or at Snorkel 101 Camp (ages 10-12) and learn all about the amazing gathering of these sharks in our local waters, and how the mystery of the La Jolla Shores Leopard Sharks was cracked by Scripps PhD student Andy Nosal, now a professor at USD!

Or if you’re a 6th or 7th grade teacher, book a Shark Science class and learn all about this phenomenon in person! 

You’ll also get to snorkel with leopard sharks at SeaCamp!
