Scientists have identified nine previously unknown deep-sea sponge species in the Gulf of Alaska and the Aleutian Islands, expanding the region’s documented marine biodiversity to 232 known species. The discovery highlights the richness of largely unexplored underwater ecosystems, though researchers warn these fragile habitats face growing threats from industrial activities. Bottom trawling and proposed seafloor mining expansions—including plans under a former U.S. administration—pose significant risks to the delicate sponges and their environments. The findings underscore the urgent need to balance exploration with conservation in vulnerable deep-sea regions.


But their habitat is threatened by bottom trawling in the region and Trump’s plan to expand seafloor miningScientists have discovered nine new deep-sea sponge species off Alaska, offering new insights into the region’s largely unexplored marine biodiversity.The National Oceanic and Atmospheric Administration (Noaa) announced the discovery on Thursday, saying the species were found in the Gulf of Alaska and the Aleutian Islands. The findings bring the total number of known sponge species in Alaska to 232. Continue reading...
