DESCRIPTION: "They even had one of the rare and famous bolas-birds, the only flying creature of any size native to Venus, with infra-red-sensitive eyes to pierce the mists. It carried three bony structures dangling from its body on tough strings of cartilage; these were used as a weapon much like the ancient Argentine bolas, to ensnare victims. The bolas-bird was its own worst enemy, frequently strangling itself in the excitement of a chase." ("The Dual World" by Arthur K. Barnes)

NOTES: Another Venusian creature mentioned in passing.
