Local photographer Rebecca McCall shared four of her diving photos with the Daily News, some of which will be featured in Picture Perfect.
She encountered the hammerhead shark about 20 miles off the coast. "He was about 11 feet in length," she wrote. "He was not shy which is rare for a great hammerhead. They typically keep their distance from divers. I spent about 40 minutes with this incredible animal before he swam off into the distance."
One photo shows a sea turtle dining on a jellyfish.
"The seahorse was about 15 miles offshore and in about 40 feet of water. Also rare to find while diving but always a treat."
She said it was like being on a treasure hunt when she spots one.
