There is also The Lizard Man of South Carolina, The Squonk of Pennsylvania, and the Chupacabra of Puerto Rico.
I can’t speak for other specific nations besides Nessie in Scotland or The Abominable Snowman in the Himalayas, but all areas of the world have stories of Were-Beasts. Europe has Were-Wolves, Native Americans have Were-Bears, Africans have Were-Lions and Were-Cats, Asians have Were-Tigers, and we all have beings in human form who act like wild beasts. (The last are very real.)
As much as real animals leave behind such as hair, dandruff, scales,teeth marks in food, claw marks in trees, blood, utine, scat,and all the genetic material we now know from these, you’d think that stories of Cryptids would no longer have sway with people anymore, but alas they do.
