Crocodilians found in Massachusetts are nothing new, as evidenced by this file photo from that state.

Wildlife officials are on the lookout for an alligator that is rumored to have taken up residence in a Massachusetts pond. Department of Conservation and Recreation officials searched Silver Lake in the Breakheart Reservation park in Saugus on Thursday, July 28, 2011, after two alligators sightings, S.J. Port, spokeswoman for the DCR, told the Boston Globe. No alligators were found.

Port said one sighting was reported on Monday, July 25th, and another sighting was reported in June.

You might wish to avoid swimming in Silver Lake for awhile.
