Which type of shark is very uncommon has a long pointed snout and lives in very deep water?

The shark you are referring to is likely the Goblin shark. Known for its distinctive long, pointed snout and unusual appearance, the Goblin shark is a deep-sea species that is rarely seen by humans. It inhabits depths of around 100 meters (328 feet) to over 1,200 meters (3,900 feet), primarily in the waters off Japan, though it can be found in other deep ocean regions. Its unique adaptations make it a fascinating subject for marine biologists.
