NOAA Scientists Discover Nine New Deep-Sea Sponge Species Off Alaska

Published

Just the facts

Scientists analyzed marine specimens gathered as far back as 2012, publishing their findings across two scientific journals to expand Alaska's known sponge count to 232 species. Researchers utilized microscopic skeletal examinations and genetic DNA barcoding to successfully classify and reference the newly identified marine organisms. Dense sponge gardens function as critical fish habitats by filtering seawater and providing physical shelter for commercially vital crab and groundfish species. Environmental groups noted that these fragile seafloor ecosystems face potential environmental threats from bottom-trawl commercial fishing and proposed seafloor mineral mining initiatives.

Why this is news

Researchers with the National Oceanic and Atmospheric Administration Fisheries announced the discovery of nine new deep-sea sponge species off the coast of Alaska. The new species were identified from samples collected during annual bottom-trawl surveys in the Gulf of Alaska and the Aleutian Islands.
