Scientists have filmed a live goblin shark in its natural habitat for the first time. The team from University of Hawai'i at Mānoa observed two healthy sharks, one near Jarvis Island and another in the Tonga Trench. This discovery expands our knowledge of this rare species.

For the first time ever, scientists have seen a goblin shark alive in its natural deep ocean environment. The team from University of Hawai'i at Mānoa made this historic observation. Until now, all confirmed videos or observations of live goblin sharks were made after they had been caught on fishing lines and brought to the surface.

The new research, published in the Journal of Fish Biology, reports two healthy goblin sharks observed in the wild. One was seen near a seamount close to Jarvis Island, while the other was recorded along the slope of the Tonga Trench. Goblin sharks are often called 'living fossils' because they belong to a family that dates back nearly 125 million years.

The team used a remotely operated vehicle (ROV) to capture video footage of the sharks. The ROV is like an underwater robot that can dive deep into the ocean and record what it sees. One of the sharks was seen swimming near a seamount northwest of Jarvis Island, while the other was recorded in the Tonga Trench.

The team's lead author, Aaron Judah, said that seeing the goblin shark alive in its natural habitat is a unique honor. He also mentioned that the observation from the slope of the Tonga Trench is nearly 700 meters deeper than this species was known to live.

Why It Matters

This discovery is important because it helps us learn more about these rare and mysterious creatures. It also expands our knowledge of their habitat and behavior, which can help us protect them and their environment.

Key Facts

• Goblin sharks are one of the rarest and most mysterious shark species in the world.
• They belong to a family that dates back nearly 125 million years.
