Yes, they're quite real. In fact it's one of the largest shark families out there, with around 160 species.
But are they catty? No, but they are fond of cat's-eyes. Chiefly because of their own eyes are very cat-like in appearance. Not everyone seems to think so though, as some species of catsharks are also know as dogfish for some reason. Of course, no species of this family has been observed barking or meowing...yet.
One humorous characteristic of catsharks is that tooth regeneration in the lower jaw of juveniles is dependant on the sonic hedgehog protein (that's what it's called).
Quite fitting too, since shark teeth grow really quickly. Gotta bite fast!

It's understandable if people like fish sticks tough, and if they like having them in their mouths.

It had to have started somewhere.

Oh the savagery!

Alternatively, Froppy derailing Shark Week.

Gura really needs to tone down this dangerous, imitable behavior. What if some young impressionable sharks watching her decide to it, and they get hurt as a result?

Good thing he caught her. Who knows how many victims she would have killed with her cuteness.

Just don't do it until they run out of breath.

But are hammerheads immune to getting hammered?

I guess that's what so great about them. Now, as for what's so white....

I feel like there's some clever French-language pun to be made with "que." Sadly, I do not posses the linguistic aptitude to do so.

Sorry, I'm all booked on existential crises for the moment. I may have an opening in a month or...never. Still, that is a interesting fact. Like that shark who's nearly 400 years old.

Wait 'till she gets to 80. But yeah, I always forget 15 and 16, too.

C'est ne pas vrai. Je ne peux pas le croire.

We interrupt Shark Week to bring you...the French. Aaaah, the French, always celebrated for their contributions to the ideals of modern liberal democracy.
The National Day of France, also called Bastille Day in English, celebrates the storming of the eponymous political prison on the 14th of July 1789. Though holding only 7 prisoners at the time, it was seen as symbol of royal authority and oppression. Its fall galvanized the French Revolution and the subsequent transition of France from a monarchy to a republic.
The pictured painting is, fittingly enough, called "Storming of the Bastille" by Jean-Pierre Houël. (May have to summon @purplepumpkin for more details.)
This holiday is usually celebrated with parades, air shows, and fireworks. (Not sure if they re-enact the Bastille battle as well.)

When is this from though? Just last week I got a weather warning from the game over a light drizzle.

It appears so. But further practical research into this subject may be necessary.

Will the carnage never cease?

Tell me something, my friend. You ever dance with an apex predator in a pale aquarium tank?
