How a hidden mountain fuels a massive Pacific shark gathering

Thousands of Sharks Gathering | Blue Planet | BBC Earth · 4:15 · Video: BBC Earth · Watch at the source

In short: Discover the extraordinary food chain triggered by a submerged mountain 300 miles from the shore. This video explores how plankton and tuna attract thousands of sharks to a single Pacific location.

Beneath the waves of the Pacific, a tiny island sits 300 miles from the coastline, masking a massive underwater mountain. This geological feature creates a thriving habitat for thousands of fish that feed on plankton.

This concentrated food source drives a complex ecological chain: plankton attract fish, which in turn attract tuna, ultimately drawing thousands of sharks to the area, including Hammerhead sharks.
