The idea of extinction -- the permanent loss of life -- is frightening. Yet the stakes of losing plants and animals are often unclear. If an already-rare bird vanishes from the forest, most people probably won't feel the impact.
But a troubling situation unfolding in Florida is different. Following a record-shattering heat wave in 2023, two marine species are now nearly extinct in the state -- and the impact of that loss on human life will likely be felt for generations.
In a new study published this week in Science, researchers found that elkhorn and staghorn corals -- two species once fundamental to the structure of Florida's reef -- are now "functionally extinct" in the state. That means these animals are so rare that they no longer serve a function in Florida's marine ecosystem.
Why extreme heat kills corals
Corals are colonies of living animals, known as polyps, that have a symbiotic relationship with a kind of algae that lives inside their cells. The algae give coral food -- and their color -- in exchange for nutrients and a place to absorb sunlight.
