They have a great sense of smell. And while it is super great, I don't know the total number of like, you know, they can smell one cent and the gal million gallon or something. And yeah, I try to get away from the whole drop of blood. Because it's really not what they're smelling. It's more of like the the food proteins that they're keying into. Yeah, cuz a lot of people are like, Oh, my God, if you have a cut on your hand, should you be swimming with the sharks and like this, no big deal, they really don't care. It's like, the proteins in your blood are not a food item for sharks, so they're not actively looking for it. So you're fine with a cut. I have dove many times in Shark lagoon with like, you know, I'm pretty clumsy human being so I get cut on my hands. And none of the sharks have taken any interest in me safe at all my hands. And, yeah, so their sense of smell is good, but not nearly as good as their sense of hearing, they're hearing as much better. They're actually very sensitive to hearing so much so that when you're building and designing an exhibit for them, you really have to take into consideration sound and noise and vapor vibrations from like pumps and other filtration components.
