Cropan’s Tree Boa
Very often in the Brazilian region of Ribeira Valley, farmers who encounter snakes kill them. Only after that do they send them to researchers who are always keen to research the species in more detail. Luckily in 1955 a group of farmers saw this rare snake and captured it alive. For more than 100 years they believed that it didn’t exist anymore.
Narwhal
It’s definitely shocking to see the narwhal on this list as they’re considered a myth but lo-and-behold, here we are. They were officially found by historian Olaus Magnus back in 1555 thus shattering the belief that they were a myth. Due to rising levels of global warming, these beautiful creatures are approaching the endangered species list yet again.
