Rarely seen or caught, the Pink Goblin Shark lives at great depths of around 1300m.  Of all shark species, this one stands out due to its long spade-like nose. This is covered in tiny pits that detect electrical impulses.  This sense is probably used to locate prey, but may also make electrical communication cables lying on the sea bed attractive to the sharks. A Goblin Shark tooth has been found in a cable 1400 m below the surface, showing the extreme depths to which this shark can swim.
