It is difficult to predict which animals will go extinct in a specific year, as the extinction process is complex and can take years or even decades. However, there are many animal species that are currently endangered and in critical need of protection. Here are some of the most endangered animals in 2023 according to various sources:

• Amur Leopard: This is the worlds most endangered big cat, with only around 84 individuals left in their natural range.
• Saint Lucia Racer Snake: The worlds rarest snake, with a global population as low as 20. It was almost wiped out by the arrival of the Asian mongoose, introduced in the late 19th century.
• Red Wolf: The worlds most endangered wolf, with only 15-17 individuals left. Once common in eastern and south central regions of the US, the red wolf was listed as a species "threatened with extinction" under the Endangered Species Preservation Act in 1967.
• Tiger: Tigers are one of the closest big cats to extinction, with fewer than 3,900 remaining in the wild. They exist in only 4% of their historic range.
• Orangutan: Orangutans are critically endangered due to habitat loss from deforestation and palm oil plantations. There are only around 100,000 left in the wild.
• Leatherback Turtle: The largest sea turtle species, with a global population decline of over 80% in the last three generations. They are threatened by habitat loss, egg harvesting, and accidental capture in fishing gear.
• Vaquita: The worlds most endangered marine mammal, with only around 10 individuals left. They are threatened by illegal fishing practices in the Gulf of California.
• Javan Rhinoceros: The rarest of the five rhino species, with only around 72 individuals left in the wild. They are threatened by habitat loss and poaching for their horns.
• Goliath Frog: The largest frog in the world, with a global population decline of over 50% in the last three generations. They are threatened by habitat loss and over-harvesting for food and the pet trade.
• African Pangolin: The most trafficked mammal in the world, with all eight species threatened by poaching for their scales and meat. They are also threatened by habitat loss and the bushmeat trade.

It is important to note that this is not an exhaustive list and there are many other animal species that are also endangered and in need of protection.
