  1. Carbon pollution has fuelled ‘massive expansion’ of marine heatwaves in Europe, study finds
    By Ajit Niranjan Europe environment correspondent

    Hottest periods this year in most sea regions would have been ‘virtually impossible’ in a preindustrial climate

  2. Descubren nueva especie de coral cerca de la Isla del Coco

    Una nueva especie de coral fue descubierta en aguas profundas cercanas a la Isla del Coco. El hallazgo es de tal importancia que los expertos tuvieron que crear una nueva familia y un nuevo género biológico, debido a las diferencias morfológicas y moleculares de este animal marino. La especie fue encontrada específicamente entre los 360 […]

  3. ¿Y los protectores solares minerales, esos que prometen ser la alternativa natural? Cuidado. La agencia estadounidense de medicamentos #FDA solo reconoce como seguros y eficaces el óxido de zinc y el dióxido de titanio –pero eso se refiere a la seguridad para nuestra piel, no para el #coral. Los propios autores del trabajo en #Science lo dicen sin rodeos: no está nada claro que los filtros solares metálicos sean más seguros para los arrecifes que los orgánicos

  4. Lo que sabemos sobre el impacto de los #protectoressolares en los #corales Antonio Figueras Huerta, Instituto de #InvestigacionesMarinas (IIM-CSIC) En mayo de 2022, un equipo de la #UniversidaddeStanford publicó en Science: La #oxibenzona absorbe la radiación ultravioleta y disipa la energía en forma de calor El problema es que, cuando entra en las células de una anémona o de un #coral, el animal la metaboliza: le engancha una molécula de azúcar y la transforma en un compuesto

    "Corals Spin Tiny Vortices to Get Oxygen, but Not if It’s Too Hot

    At first glance, corals present as little more than colorful rocks — piles of lobes, stalagmites, and branches poking out from the seafloor.

    They are anything but. Corals are complex creatures that form enduring colonies, and just like other animals they need oxygen to live. Across the living surface of coral, a frantic dance of survival takes place, invisible to our eyes and unknown to science before 2014. The tiny dancers are hairlike cilia, and new research into these microscopic structures is revealing just how active corals are in determining their own fate.

    Corals aren’t fortunate enough to have a consistent supply of oxygen, and they can’t change location to seek it out. During the day, the tiny polyps that make up a coral colony get plenty of oxygen from the symbiotic algae that photosynthesize within their tissues. But at night that process stops, and a coral polyp’s only source of oxygen is the water around it. Then it’s do or die for the cilia. Using mechanisms scientists are still trying to understand, the cilia wave around to generate fast-moving vortices of water that circulate oxygen to the coral’s outer tissues, in addition to helping keep the colonies free of sediment.

    A study published in Science (opens a new tab) in May 2026 provides new insight into how organisms with no brain or musculoskeletal system can generate and regulate this process — and what happens when the water around them warms up. Warmer water naturally carries less oxygen, which prompts corals to move their cilia faster and faster, as if gasping for breath. Above a certain temperature, the system starts to work against itself; the furious beating of cilia uses up any oxygen the coral’s tissues can absorb, and then the polyps can suffocate in the less oxygenated water. Biophysicists, marine biologists, mathematicians, and modelers are now collaborating to better understand the physiological and hydrodynamic forces at work, and how they correlate with bleaching patterns, coral disease, and mass die-offs."

  6. Pulsing Xenia (Xenia species), a soft octocoral. Xenia is famous for its feathery, eight-tentacled polyps that rhythmically contract and expand. This unique motion aids in driving gas exchange, waste expulsion & localized water circulation enhancing photosynthesis. #ocean #coral #animals #biology #science
