Iara is a type of mermaid from the myths of Brazil. She is said to sit on a rock in the Amazon river and brush her hair until a man comes along. At which point she will start singing to lure him in. The man would give up everything to go and live with Iara for the rest of his life as she would cater to all his needs. In other versions though she will lure men in and drown them. Unfortunately for Iara, she is immortal so she will always outlive any lover she might have. Iara was commemorated in Brazil by being put on the stamp in 1974.

In Iroquois mythology, the Jogah are a type of dwarfish nature spirits standing around knee-high. They are most often invisible but are known to reveal themselves to children medicine people or the elderly. They have been known to be helpful towards those that they like or have been left offerings by. Jogah are the grandchildren of the thunder god Hinun, who is the leader of the Thunders, a clan of storm spirits.

There are three different kinds of Jogah, one of them is called Ohdows which are gnome-like and live underground keeping animals like snakes under control. Another is the Gahongas which means Stone Throwers, these spirits are very strong and move rocks around the countryside and live in caves or along rocky riverbanks. The last kind is called Gandayah (Drum Dancers) the only way for the Iroquois to know of their presence is by the sound of them playing drums. They control the flora and help farmers with their crops.

The Clurichaun is the sort of drunken cousin of the Leprechaun. They usually reside in wine cellars and bars and always have a drink in their hand. They are said to have faces like withered apples and noses that are purple from all the drinking. Clurichauns will also attach themselves to certain families, especially ones that have a wine cellar.

In the folklore of the Shetland Islands, the Wulver is a type of benevolent werewolf. Its appearance is described as a furry person with a wolf's head. It does not transform from man to wolf or vice verse but is always in the same form. Wulver would sometimes have a rock out on the water that they would sit and fish on. From time to time a Wulver will leave fish on the windowsill of poor families.

However, it is believed that Wulver is an accidental creation due to a mistranslation of the word Wulver (old Norse) which was a hill named after a fairy.

In American, Canadian, and Australian folklore, the Hoop Snake is a venomous snake that puts its tail in its mouth (like Ouroboros) and chases after prey. When it is within striking distance, the Hoop Snake straightens out and impales the victim with its tail. The only way to avoid the blow is to hide behind a tree, which dies immediately from the poison. The Hoop Snake also appears in stories of Pecos Bill (American Cowboy folk hero).

The Hoop Snake was mentioned in a letter published in the Tour in the U.S.A. Vol. 1:

"As other serpents crawl upon their bellies, so can this; but he has another method of moving peculiar to his own species, which he always adopts when he is in eager pursuit of his prey; he throws himself into a circle, running rapidly around, advancing like a hoop, with his tail arising and pointed forward in the circle, by which he is always in the ready position of striking.

It is observed that they only make use of this method in attacking; for when they flee from their enemy they go upon their bellies, like other serpents".

In Scottish folklore, the Ghillie Dhu is a type of solitary male fairy and is described as being short with dark hair. This fairy lives inside birch trees near a place called Loch a Druing which is close to Gairloch. He wears clothes made out of moss and leaves and helps children that become lost in the woods find their way out. Its name also became the inspiration for the Ghillie Suit.

In Japanese folklore, the Tomokazuki, whose name means "diving with" or "together-diver" are found deep in the oceans. Women called Ama gather things like sea urchins and oysters by doing deep dives. On cloudy days they will come across one that has taken on their form but will be wearing a longer headband.

The Tomokazuki beckons divers closer to them with offerings of what they're trying to collect. They lure them deeper in the hopes of the women straying too far from shore and drowning. Some people believe that these creatures are the drowned spirits of other Ama. One way to protect yourself against them is to put the symbol of either seiman or dōman on your headband before you go diving.

The Huma is a bird in the mythologies of Iran, Persia, and Turkey. It is said to not have any legs and lives its entire life in the sky. Every few hundred years this bird will consume itself in fire like a Phoenix and be born again. It is a bird of fortune and anyone who sees it is said to be happy for the rest of their life, but if a person takes the life of the Huma bird they will die in forty days. If a Huma bird's shadow goes over someone's head or shoulder, then that person has been bestowed kingship. 

Preface: I have not been able to verify the legitimacy of this myth outside of the one person who told it (only told orally in the tribe) but I do still think it is an interesting myth worth sharing. They said they are from a 'sub-tribe' of the Abenaki people and learned of this story through their grandma. I reached out to the person who posted it but never got a response back in hopes of more information. 

In Abenaki folklore, there are spirits called Water-Faced Hunters. They look like people but their faces are a pool of water that reflects your face or the face of someone you know so they can lure you away to drown you. They normally only hunt during thunderstorms. These spirits are believed to be people who died by drowning. The Water-Faced Hunters will attack you if you acknowledge them. To avoid doing so, try not to interact with them at all and keep going on your way. This could be used as an explanation for how people are found far from water but look as though they have been drowned (like in a flash flood).

This lake monster, whose name means water horse, is similar to that of the Scottish Kelpie. It lives in Loch Suainbhal on the Isle of Lewis, Outer Hebrides. It has been described as looking like a capsized boat and sightings have been reported for centuries. However, some reports claimed it to be up to 40 feet in length and similar in shape to an eel. A Zoologist by the name of Cyril Dieckhoff, thought that it might be nothing more than a Conger Eel (though the largest ones are under 10 feet in length) and locals claimed that it was so large that a 6-oared boat could pass between its fins. It has been said that locals used to sacrifice lambs to it annually to appease the monster. 

On the Scottish island of Benbecula near the town of Griminish, there is a story of a mermaid who was murdered by the locals. The mermaid was spotted by a woman who was cutting seaweed and called others over to try and catch it but it was elusive. A boy threw a rock at it which struck it on the back and it cried out in pain before disappearing under the waves.

Its body washed up a few days later on the bay in the town of Nunton the description of the mermaid is as follows: 

“The upper part of the creature was about the size of a well-fed child of three or four years of age, with abnormally developed breasts. The hair was long, dark, and glossy, while the skin was white, soft, and tender. The lower part of the body was like a salmon but without scales.” 

It was said to have been put into a coffin and buried in the nearby churchyard where it had one of the largest group gatherings for a funeral on the island.

On the isle of Lewis, in Scotland, located on Loch Langavat (Scottish Garlic Langabhat) there was once said to live a community of werewolves. They lived on an island on the loch but all of them eventually died. It is believed that if you disturb their graves they will rise from the dead (zombie werewolves!?!)

As was pointed out on a website that I was researching for this post, when one takes into account a similar myth in the area of the Wulver in Shetland folklore and the fact that Nordic people were living in the Hebrides for a time and had their werewolf myths like that of Sigmund and Sinfjotli, it is fascinating to think about. Did they somehow inspire this or was it just from the locals who were already there? Another thing to note is the myth of the Draugr which will come back to life if someone tries to steal its grave goods.

The source of this myth seems to come from a book called Scotland's Ghosts And Apparitions by Terence. W. Whitaker.
