Two-headed snakes, tourist-tossing bison and one very good dog - High Country News
Briefly

Angel and Zeke, a rare double-headed California kingsnake born in a Berkeley pet store, represent a genetic anomaly with low survival odds. Despite these odds, they are thriving at over 7 months old, consuming a baby mouse weekly and navigating their environment, albeit clumsily. The dynamics between their two heads reveal a dominant behavior during feeding. In Yellowstone National Park, the tourist-tossing season has begun, with a man injured by a bison after approaching too closely, marking the first such incident this year.
The chances for survival of double-headed snakes, such as Angel and Zeke, are slimmer than their single-headed counterparts, as the odds against polycephaly are approximately 1 in 100,000.
Angel and Zeke have already lived much longer than expected, thriving at just over 7 months old, growing over a foot long and consuming a baby mouse weekly.
Despite their unique condition, the double-headed kingsnake navigates their habitat in a somewhat clumsy manner and is described as both clumsy and fearless, with one head often dominating decisions.
This season at Yellowstone National Park saw a man gored by a bison after getting too close, marking the first of likely many such incidents this year.
