Of course, it's not called the goblin shark because of its friendly face. Indeed, this striking, pale-pinkish fish is hard to forget once you see it.
Let's start with the elongated, flat snout. Goblin sharks have tiny skin "sensors" called ampullae of Lorenzini on the snout that can sense electrical fields at even the smallest levels.
That's a useful feature, because it helps the shark track prey by cruising the sea floor and sniffing out whatever tasty voltage source might be nearby.

Meanwhile, these spooky creatures have jaws that protrude in freakish fashion – striking outward as though they're a separate thing unto themselves. The upper jaw has 26 narrow, sharp teeth, the bottom jaw 24.
If it finds prey within reach, a goblin shark thrusts extending its jaw forward and snares the poor creature.
The sharks are so hard to observe that it's not entirely certain what's in their typical diet, but researchers think fish, squid, octopus and shrimp are likely menu items.

Scientists have traced its line back some 125 million years. Today, this creature that's sometimes called a "living fossil" is the only remaining member of the Mitsukurinidae family. It was first described by fish researcher David Starr Jordan in 1898.
While rare to observe, goblin sharks aren't considered endangered, as they seem to be good at avoiding people and their wide-ranging sightings suggest they are abundant.
