Hammerheads are aggressive hunters, feeding on smaller fish, octopuses, squid, and crustaceans. They do not actively seek out human prey, but are very defensive and will attack when provoked.

nitlon:  Smallest Whale Shark Discovered — On a Leash

A local whale shark “interaction officer” cradles what is likely the smallest known wild example of the world’s biggest fish on Saturday in San Antonio, Philippines.
The discovery of the baby whale shark could help protect these rare giants by shedding light on where whale sharks are born.
Early on March 7 a project leader from the international conservation organization WWF and others in the town of Donsol heard that a live whale shark was being offered for sale at a nearby beach. Expecting a stranded giant, the rescuers found instead a 15-inch (38-centimeter) shark leashed to a stake in the mud like a neglected puppy.
By the end of the day, after photos and measurements had been taken, the young whale shark was free again, released into deeper waters.
Harmless to humans, whale sharks feed mainly on plankton and can grow to at least 40 feet (12 meters) long. They are listed as vulnerable by the International Union for Conservation of Nature, meaning they “face a high risk of extinction in the medium-term future.”

New Hammerhead Shark Species Confuses Conservationists
There’s good and bad shark news. The good news is that a new, as of yet unnamed, species has been discovered. The bad news is that it looks just like the scalloped hammerhead shark, curtailing efforts to save that endangered species.
The new look-alike hammerhead is identical to its near twin save for a few important differences:
distinctive DNA
20 fewer vertebrae (about 170 versus 190)
a genetic profile suggesting it separated from the scalloped hammerhead 4.5 million years ago
That’s an incredibly long period of time, considering how similar the two different sharks look externally.
