Officials at a non-profit aquarium in Idaho allegedly turned to illegal trafficking to stock its exhibits.

Earlier this week Ammon Covino, 40, and Christopher Conk, 40, pleaded guilty to conspiring to transport spotted eagle rays and lemon sharks from the Florida Keys, knowing they were intended to be sold in violation of law.

According to authorities, both men were officers at the Idaho Aquarium in Boise in 2012 when they directed a company in Florida to send the sea critters from the Keys to Idaho and bypass the state permit process required for the shipments. They paid using the aquarium’s credit cards, court records state.

What the two didn’t know was that the business owner was cooperating with federal authorities, and the phone conversations and text messages were recorded.
