For example, a relatively recent outbreak termed stony coral tissue loss disease is an apparently infectious waterborne disease known to affect at least 20 stony coral species. First discovered in 2014 in Miami-Dade County, the disease has since spread throughout the majority of the Florida s Coral Reef and into multiple countries and territories in the Caribbean. Some reefs of the northern section of Florida s Coral Reef are experiencing as much as a 60 percent loss of living coral tissue area.

Lagoon insights come from hearing rays

Atlantic whitespotted eagle rays are some of the most stunning, mysterious bottom feeders found in Florida. But until now little has been known of where they go, what they eat and their other sundry, barbarous ray ways. But recently biologists listened to the Indian River Lagoon, carefully, and with sophisticated sound devices, they could hear the voices of the rays  fish that don t speak but definitely have a story to tell. What scientists heard? Our lagoon is one of a ray s favorite places. While the researchers technological feat heralds new hopes of discovery, it also harkens back to old worries. The technology helps us tobetter to understand this otherwise mysterious creature that munches down lots of the same seafood we do. But by confirming that spotted rays really prefer inland waters like the lagoon, we now know the fish is in much greater danger of suffering from pollution than we previously thought.

Drifter or homebody? Study first to show where whitespotted eagle rays roam

Researchers from Florida Atlantic University s Harbor Branch Oceanographic Institute in collaboration with Mote Marine Laboratory & Aquarium, the University of Florida and the Florida Fish and Wildlife Conservation Commission, are the first to conduct a multiyear study examining large-scale movements of whitespotted eagle rays in United States waters.
