Bottlenose dolphins are known for their natural curiosity and playful nature. As a result, it is not unusual to find a pod suddenly appear near a group of bathers. Seals and the Jersey Shore Seals are common along the Jersey coastline from November to April when they migrate south from the colder arctic climate. However, sometimes an individual decides to spend the summer here, like this Harbor seal. Harbor seals can grow to 6 feet long, are tan and dark brown and usually seek out places with little human contact.
Grey seals are less common, but are frequent visitors to New Jersey waters.
They can weigh as much as 800 lbs. and grow to 8 feet. Harp seals can also be found at the New Jersey coast in the winter. An adult Harp seal can grow to 6 feet and weigh around 400 lbs.
