- 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 hiding 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-built underwater robot deployed on a coral reef in 2026 located a single coral pillar supporting nearly 25 times more fish than surrounding areas, and used reef sounds to navigate and identify healthy habitats. Researchers say acoustic tracking could help target conservation and restoration efforts. The findings are drawing attention to how robotics and bioacoustics can map ocean life.
- 3Bacteria on coral reef fish gills carry chemosynthesis genes●DNA reveals chemosynthesis genes in bacteria living on coral reef fish gills
Researchers have found that bacteria living on the gills of coral reef fish carry genes for chemosynthesis, meaning they may be able to produce energy from chemicals rather than light. The discovery, reported by Phys.org, suggests fish gills could host microbial communities with an unusual metabolism, expanding what scientists know about where chemosynthetic microbes live.
