Turtles at a park in Washington state were found with swastikas painted on their shells — and wildlife officials are struggling to catch the offensive critters so they can be cleaned off, according to a report Thursday.

The Nazi symbol was scrawled in white on the backs of several of the reptiles at Gene Coulon Park in Renton, stunning visitors who spotted them sunning on rocks, according to krio7.com.

“It sits with you uncomfortably,” one park-goer huffed to the local station.

Police received calls about the anti-Semitic snappers and tried with no luck to wrangle them, according to a Renton Police Department Facebook post.

The city is now getting help from federal wildlife officials to catch and clean them off, according to the station, which noted the tagged turtles had been seen at the park’s lake for more than a month.

Lovers of the great outdoors called turtle shells an unlikely canvas for hate.

“It’s very bizarre,” park-goer Aaron Greene said. “What’s going on?”

But whoever painted the symbol isn’t the brightest of bigots.

“It appears [the swastika] may have been painted in the wrong direction,” said Miri Cypers, a rep for the Anti-Defamation League.
