The Florida Reef stretches approximately 360 miles from Dry Tortugas National Park west of the Florida Keys to the St. Lucie Inlet in Martin County. This area faces imminent danger from an outbreak of coral disease termed stony coral tissue loss disease. Already in decline due to degraded water quality, climate change, and an expanding South Florida population, the reef has become the focus of a crisis intervention led by dozens of partners from federal, state, and local agencies; non-governmental organizations; universities; and members of the community.
SeaWorld is among those actively combatting this destructive disease in an ongoing effort to support and protect the environment. Historically, SeaWorld has established numerous resources and funds to help support environmental conservation.

Sharks are also known to have a fine-tuned electrosensing ability that helps them detect prey
Forget Google Maps sharks can read the Earth’s magnetic field like a GPS navigator to find their way, a study in Current Biology showed Thursday.
Lead author Bryan Keller told AFP the paper vindicates a decades-old theory about how the aquatic predators are able to migrate vast distances, swim in arrow-straight lines, and return to their precise point of origin.

Sea turtles are known for relying on magnetic signatures to find their way across thousands of miles to the very beaches where they hatched. Now, researchers reporting in the journal
Current Biology on May 6 have some of the first solid evidence that sharks also rely on magnetic fields for their long-distance forays across the sea. It had been unresolved how sharks managed to successfully navigate during migration to targeted locations, said Save Our Seas Foundation project leader Bryan Keller, also of Florida State University Coastal and Marine Laboratory. This research supports the theory that they use the earth s magnetic field to help them find their way; it s nature s GPS.

(CN) Researchers have found new evidence showing that much like sea turtles, salmon and lobsters, sharks use magnetic fields to help guide them as they journey across the sea.
“It had been unresolved how sharks managed to successfully navigate during migration to targeted locations,” Bryan Keller of Florida State University Coastal and Marine Laboratory said in a statement.
Keller is the lead scientist and author of the study published Thursday in the journal Current Biology.
“This research supports the theory that they use the earth’s magnetic field to help them find their way; it’s nature’s GPS,” Keller added.
