Chappy, a baby gray seal pup who was found on Feb. 16 stranded on the streets of New Haven, Connecticut, by police, has died after suffering severe digestive issues, according to the Mystic Aquarium who had been treating him since he was discovered last month.

The aquarium helping Chappy — a nod to the New Haven, Conn., neighborhood where he was rescued last month — said he died of gastrointestinal issues and "was surrounded by love until the very end."
