"John Carter and the Giant of Mars" by Edgar Rice Burroughs

DESCRIPTION: "The tree reptile launched itself straight for the hated man-things...A huge claw knocked him lying on the ground with the great fangs at his throat." ("John Carter and the Giant of Mars")

NOTES: The arbok lives in the rare forest of Mars. Its fangs are venomous.

HISTORY: This ill-defined monster shows Burroughs love of word-play. Arbok is Kobra backwards. The name was taken for a Pokemon in the 1990s. It only appeared once in the first chapter of "John Carter and Giant of Mars", one of the most controversial of Burroughs' stories. For many years it was considered a fake, but its history was revealed to be a genuine Burroughs written for Whitman's Big Little Book series by Burroughs and his son, John Coleman Burroughs, who illustrated the book. ERB sold a lengthened version to Amazing Stories in 1940."
