Here are a few contenders, with explanations of what makes them unique:
* The Olinguito (Bassaricyon neblina): This adorable, raccoon-like mammal was only discovered in 2013. They are found in the Andes Mountains of South America and are known for their fluffy fur and nocturnal habits.
* The Saiga Antelope (Saiga tatarica): This critically endangered antelope is famous for its enormous, bulbous nose. Their population has dwindled drastically due to poaching and habitat loss.
* The Okapi (Okapia johnstoni): This mammal is often called the "forest giraffe" due to its long neck and striped legs. It lives in the dense rainforests of the Democratic Republic of Congo.
* The Solenodon (Solenodon paradoxus and Solenodon cubanus): These venomous, nocturnal mammals are found only in Cuba and Hispaniola. They are one of the few venomous mammals in the world and are often called "giant shrews".
* The Blobfish (Psychrolutes marcidus): While this fish is often depicted as a bizarre, gelatinous creature, it's actually adapted to live at extreme depths in the ocean, where its blobby appearance helps it float. It's not technically an "unknown" animal, but many people may not know about its unique adaptations.
Ultimately, the "most obscure" animal is subjective. There are countless lesser-known species waiting to be discovered and studied!
