This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Bahamut (Arabian)
Bahamut, or Bahamoot, is a monster that lies deep below, underpinning the support structure that holds up the earth. In this conception of the world, the earth is shouldered by an angel, who stands on a slab of gemstone, which is supported by the cosmic beast (ox) sometimes called Kuyutha. Bahamut carries this bull on its back, and is suspended in water for its own stability.
Bahamut, is a giant fish acting as one of the layers that supports the earth. It is so immense "[all] the seas of the world, placed in one of the fish's nostrils, would be like a mustard seed laid in the desert." Above the fish stands a bull called Kuyootà, on the bull, a "ruby"[e] rock, on the rock an angel to shoulder the earth. Below the Bahamut (Leviathan) is the colossus serpentine Falak.
