Planning to sail around the Statue of Liberty? Watch out for whales. The Coast Guard issued a warning to boaters saying as much after a whale was spotted near Liberty Island on Thursday, the AP reports. "We have no confirmation on what type of whale it is and we don't know where the whale is currently," a Coast Guard spokesperson tells the New York Daily News, noting that the whale was only seen once. "It’s rare to have them inside of New York Harbor," says a rep for a marine life-tracking group in the area. "It was probably chasing fish inside the harbor and ended up staying there because that’s where they fish are." (More New York stories.)
