New study shows coral polyps use cilia to whip water into vortices that bring oxygen to their tissues when photosynthesis from symbiotic algae isn’t active; as water warms, cilia move faster to compensate, but at higher temperatures they consume oxygen faster than it’s available and eventually slow or stop, linking heat to reduced oxygen delivery and contributing to bleaching and mortality in reefs.
A recent study using a deep-sea chemiluminescent sensor called SOLARIS has revealed that deep-sea corals and sponges produce reactive oxygen species (ROS), specifically superoxide. This discovery suggests that these chemicals have previously unknown effects on ocean life and chemistry in the deep sea. The study also found that the production of superoxide is not solely a stress response but a fundamental part of the corals' regular life functions. The findings have implications for understanding coral health and activity, as well as how coral ecosystems may respond to climate change.
In an effort to save Florida's dying corals, a swarm of Caribbean King Crabs will be introduced to the Keys. These crabs, known for their voracious appetite for coral predators, are expected to help restore the delicate ecosystem by preying on the coral-eating snails that have been devastating the reefs. The project aims to protect and revive the coral reefs, which are crucial for marine biodiversity and tourism in the region.
