And this is a response to really good efforts at shark management by both federal and state authorities and others that we're not necessarily seeing the population trajectory we would hope to.
So for some really depleted shark populations, the rebuilding plans are really very long term.
It's after 2100 that we're hoping to see dusky sharks recover.
This is so difficult.
This is so difficult.
That's like asking an impossible question.
But I usually like to tell people about how incredibly ancient sharks are.
Sharks have been on this planet for longer than trees.
But the one that really gets me is that they're older than the rings of Saturn.
So sharks are an extremely ancient lineage of fish and they've survived many mass extinctions.
They're still here.
They're still amazing.
People often think that means that they're primitive as kind of an insult.
But in fact, the way that evolution works is if something works really well, it doesn't change.
And so rather than thinking about sharks as a group of animals that haven't evolved, I think it's more helpful to think about them as a group of animals that made good design choices very early.
You're asking the wrong person because every cool fish is special.
Okay, well, what makes them special?
So there are a bunch of things that make them distinct, but normally the reasons that the public thinks about them as special is because of their predatory role in ecosystems.
And for some species, they're very large size.
So if you ask someone to name shark species, I have a lot of experience with this.
