Dugongs or sea cows are now threatened with extinction, according to the IUCN Red List.
These gentle cousins of the manatee graze on seagrass in shallow coastal waters, and are an important source of ecotourism in their tropical habitats.Dugong populations in East Africa and New Caledonia have now entered the IUCN Red List as"critically endangered" and"endangered," respectively.Their primary threats are unintentional capture in fishing gear in East Africa and poaching in New Caledonia, as well as boat injuries in both locations.
The updated list comes as delegates from across the world meet in Montreal for a UN biodiversity conference to finalize a new framework for"a peace pact with nature," with key goals to preserve Earth's forests, oceans and species. Climate change is driving ocean acidification as well as deoxygenation, while flows of agricultural and industrial pollution from the land are causing significant impacts on ocean species, effects that cascade throughout food webs.
Abalone species are considered gastronomic delicacies, leading to unsustainable extraction and poaching by international organized crime networks, for example in South Africa.
