Blathers will say this upon donation of the shark:
"Shark flesh is often used in processed seafood products, eh wot? As such, you might wonder why it isn't grilled like other fish, am I correct? Well, shark tends to reek of ammonia, you know. And that is NOT good."
In City Folk
"If one were so inclined, one could sit around pulling shark teeth all day. They simply keep growing back! I've heard that over a shark's lifetime, it will go through thousands of teeth, which is disconcerting. ...Anyhoo, no toothpaste needed! How appropriate for a creature that's been around since the dinosaurs!"
In New Leaf
"The triangular teeth of sharks appear to have evolved from scales sometime in the past. When a tooth breaks, it quickly falls out and a new one grows in, keeping them always in good shape for prey. Sharks can be fearsome creatures, able to smell blood from several miles away. They can even jump out of the water to catch prey, making them powerful predators. Contrary to their tough image, their bones are made of cartilage and erroneously used as health food."
In New Horizons
When donating to Blathers or selecting "Tell me about this!" in New Horizons, he will provide the following information about the fish:
"Great white sharks are obviously known first and foremost for their biting. They are masters of the craft! They do lose teeth regularly through biting-related activities, but, luckily, those teeth grow back quickly. In fact, their missing teeth can be regrown in a single day. Just imagine their tooth-fairy-related income!"
The great white shark can be found in the second room once donated.
Fishing Tourney
During a Fishing Tourney, when given a shark, Chip will say the following dialogue.
In City Folk
"You can pound shark into a paste and squeeze it into wrappings for shark dogs! Nyuuuk nyuk nyuk nyuk!"
In New Leaf
"The thing about sharks is, they just go really well either fried or dried! Nice and simple like that! Yeah, even I'm not gonna attempt to down this guy all at once! What do I look like, a whale?"
The great white shark, Carcharodon carcharias, is a fish that can be found in waters all over the world in every ocean. Unlike bony fish, sharks have no bones; their skeleton is made of cartilage, which is a tough, fibrous substance, not nearly as hard as bone, but more flexible.
