Here is a list of mythical creatures beginning with this letter and I am constantly gathering information from each continent and continually updating.
Abath (Malay)
The Abath was thought to be creature similar to a European Unicorn that was first found in documents dating around the 16th century. Supposedly, Edmund Barker, a member of James Lancaster's crew traveling to East India had thought they bought several female unicorns' horn. Described as female, with a single longer horn growing from its head, it is widely believed that the Abath was nothing more then a half glimpsed Javan or Sumatran Rhino.
This abath is certainly Sumatran or Javan rhinoceros, in Malay called bada?. The the word "bada" was coined by Portuguese travelers. Ending in "a", it seemed feminine to their ears and was assigned the feminine article. Indonesian rhinoceroses had been mistaken for unicorns for a long time. Marco Polo, traveling through the kingdom of Basma, reported numerous unicorns living there, however he pointed out that those ugly, mud-wallowing brutes are very different from unicorns from European stories.
