- 1Norway Creates Its Largest Marine Protected Area●Norway has created its largest marine protected area, covering 1,848 km² of coral reefs, sponge gardens and fish nurseri
Norway has designated its largest marine protected area, covering 1,848 square kilometres of coral reefs, sponge gardens and fish nurseries. The move lifts formally protected waters from 4.8% to 6% of Norwegian territory. Discussion has focused on reports that the government drew the boundary around its salmon farms rather than through them, raising questions about how much industrial activity the new protections actually restrict.
- 2US reef robot finds coral pillar with 25 times more fish▼In 2026, a US reef robot found one coral pillar hiding nearly 25 times more fish and followed reef sounds
A US underwater robot has located a coral pillar hiding nearly 25 times more fish than surrounding reef, using reef sounds to navigate and identify hotspots. The 2026 finding suggests acoustic monitoring could transform how scientists survey reefs and prioritize conservation of dense fish habitats.
- 3Bacteria on coral reef fish gills carry chemosynthesis genes, DNA study finds●DNA reveals chemosynthesis genes in bacteria living on coral reef fish gills
Scientists have found that bacteria living on the gills of coral reef fish carry genes for chemosynthesis, the process of making food from chemicals rather than sunlight. The discovery, reported by Phys.org, suggests gill-dwelling microbes may play a previously overlooked role in reef nutrient cycles and could reshape how researchers understand symbiosis on coral reefs.
