Thursday was a tough day to own a Eurasian lynx.

Responding to what it called a recent surge in animals gone wild, New York State’s Department of Environmental Conservation moved on Thursday to label an array of exotic animals “dangerous.”

Officials proposed a set of regulations that they said were meant to clarify and codify longstanding prohibitions on a variety of dangerous game, after a rash of incidents that “posed a risk to public safety and the environment.”

The episodes included one in Wappingers Falls, in the Hudson Valley, involving a homeowner with a five-and-a-half-foot alligator and more than a dozen turtles; an Orange County man who had stockpiled more than 150 venomous snakes (including one who bit him); and a nine-foot anaconda that made a crawl for it in Suffolk County in July. (It was recaptured, thankfully.)

Supporting documents for the proposed regulations were more frightening, outlining various unsavory incidents involving animals in New York and elsewhere. They included a black mamba snake killing an upstate woman in 2011; an elementary school student attacked by a lemur in 2010; and a 2009 chimpanzee attack in Connecticut involving a 200-pound primate who had been dosed with Xanax.
