I'm sure you tour guide, and the people helping you in and out of the cage will be able to tell him what he's seeing. Off the top of my head I can think of:
in the main shark tank:
Sawtooth Fish
Brown Sharks
Pacific Black Tip Reef Shark
Sand Bar Sharks
Nurse Sharks
A Rough Tail Stingray
and Groupers (not sharks)
They also have several smaller species in their shark shallow's:
Lepoard Sharks
White Spotted Bamboo Sharks
Zebra Sharks
But thats all I can think of off the top of my head.
