![]() ![]() Other tuna species reassessed for this Red List update include the bigeye tuna ( Thunnus obesus) which remains Vulnerable, and the skipjack tuna ( Katsuwonus pelamis) which remains Least Concern. This species remains severely depleted at less than 5% of its original biomass. The Pacific bluefin tuna ( Thunnus orientalis) moved from Vulnerable to Near Threatened in this update due to the availability of newer stock assessment data and models. ![]() “Tuna species migrate across thousands of kilometres, so coordinating their management globally is also key.” Collette, Chair of the IUCN SSC Tuna and Billfish Specialist Group. We need to continue enforcing sustainable fishing quotas and cracking down on illegal fishing,” said Dr Bruce B. “These Red List assessments are proof that sustainable fisheries approaches work, with enormous long-term benefits for livelihoods and biodiversity. The yellowfin tuna meanwhile continues to be overfished in the Indian Ocean. For example, while the larger, eastern population of Atlantic bluefin tuna, which originates in the Mediterranean, has increased by at least 22% over the last four decades, the species’ smaller native western Atlantic population, which spawns in the Gulf of Mexico, has declined by more than half in the same period. The albacore ( Thunnus alalunga) and yellowfin tunas ( Thunnus albacares) both moved from Near Threatened to Least Concern.ĭespite global improvement at the species level, many regional tuna stocks remain severely depleted. The Atlantic bluefin tuna ( Thunnus thynnus) moved from Endangered to Least Concern while the Southern bluefin tuna ( Thunnus maccoyii) moved from Critically Endangered to Endangered. Four of them showed signs of recovery thanks to countries enforcing more sustainable fishing quotas and successfully combatting illegal fishing. In today’s Red List update, the seven most commercially fished tuna species were reassessed. These Red List assessments demonstrate just how closely our lives and livelihoods are intertwined with biodiversity.” “States and others now gathered at the IUCN World Conservation Congress in Marseille must seize the opportunity to boost ambition on biodiversity conservation, and work towards binding targets based on sound scientific data. “Today’s IUCN Red List update is a powerful sign that, despite increasing pressures on our oceans, species can recover if states truly commit to sustainable practices,” said Dr Bruno Oberle, IUCN Director General. They typically live 20 to 30 years.The IUCN Red List now includes 138,374 species of which 38,543 are threatened with extinction. If you see Chance, be nice: In 1952, the gila monster became the first venomous animal to be given legal protection as the species is classified as "Near Threatened" by the International Union for Conservation of Nature. Slow, but steady: Not known for their speed, gila monsters are excellent climbers which can be helpful in tracking prey.ĥ. We're confident that Chance won't bite or hiss at anyone, though. They use an open-mouth hiss to try and ward off potential predators. Gila monsters usually avoid humans and larger animals. Their hiss is worse than their bite: According to the San Diego Zoo, which houses some of the reptiles, the gila monster's bite is very painful to humans, but not fatal. It is the gila monster's ideal climate.ģ. Desert: Although images of neon lights and casinos usually fill the brain when the city of Las Vegas is mentioned, the state of Nevada is largely desert, including a portion of the Mojave, the driest desert in North America. They are usually orange and black or pink and black, but Chance obviously matches the team's colors.Ģ. It is one of just two known species of venomous lizard in North America. Scary name: Although it may be called a monster, it is actually a lizard (and pronounced HEE-la). We imagine your next question is, "What's a gila monster?" If you don't know, here are five facts to get you up to speed:ġ.
