Tracking Sharks Reveals Hidden Ecosystems
Marine biologist Austin Gallagher's research on tiger sharks in the Bahamas uncovered surprising animal behavior, as they deviated from their usual shore-hugging patterns. Instead, they were drawn to ancient underwater hills, leading to the discovery of extensive seagrass meadows. This habitat is significant, as seagrasses provide essential nurseries for fish stocks and store carbon more efficiently than tropical rainforests. The findings expanded known global seagrass coverage by over 40%, highlighting the potential for this information to aid in marine ecosystem conservation.
