Donating to the museum
When donated to the museum, this fish always goes into the back tank, the sea tank.

Blathers will comment on the player's donation as follows:

"The fin of the hammerhead shark is used in some foreign cooking, eh wot? Indeed, it is used in a delightful delicacy called shark's-fin soup! This dish is usually quite pricey because of all that goes into its preparation. Why, it takes three days merely to reconstitute the dried shark's fin! After THAT, the chef must pick out the skin and cartilage with tweezers! Only after all that can it be used as an ingredient. THAT is a just cost!"

Blathers will say this when handed the big fish:

"Ah, the hammerhead shark, also, I believe, known simply as the hammerhead in certain circles. The hammer-shaped head is thought to give this shark a great sense of its environment...like radar. Compared to other sharks, this one wears a bit of a daft expression that some people find charming!"

The hammerhead can then be found "pacing" in the back tank, much like the blue marlin.

"The hammerhead shark is a shark with a head like a hammer, which is what you'd expect. However, despite being sharks, they are actually fairly laid back, which is not what you'd expect. With their eyes positioned on the two ends of their 'hammer,' they can see in almost all directions. Oddly, their nose holes are located right next to their eyes on their hammer section. They have a number of small holes on the front and lower portions of their heads as well. These holes allow them to detect prey, even fish hiding below them and out of sight. While they eat a nice array of fish, it seems rays are their favorite source of food. Rays, beware!"

"The hammerhead shark is known for its distinctive, hammer-shaped head, hence the name. Er, obviously. Anyhoot, this oddly shaped head allows the beast to see 360 degrees around itself, from top to bottom. Imagine being able to see so widely! You could check for untied shoelaces AND imminent rain simultaneously!"

Real-world information
Hammerhead sharks are a group of warm-water sharks that are often found along coastlines. They are named for their flat, wide heads which are a distinction among the species with very little variation. Unlike most sharks hammerheads only hunt solo at night, preferring to school during the day. Their diet consists of squid, fish and crustaceans, with stingray being a favorite. Despite being a coastal shark, hammerheads rarely attack humans unprovoked. Hammerheads are often targeted for "finning", a process of cutting the dorsal fin off and releasing the shark, due to the fin's status as a delicacy.
