Delaware Bay Wildlife: Mammal Edition

The diversity of wildlife in the Delaware Bay is amazing, and on board the Cape May-Lewes Ferry, you can experience a 360-degree view of much of the marine life it has to offer! It isn’t unusual to see dolphins, so be sure to keep your eyes on the water, and pay attention to the loudspeaker as the captain will typically announce where to see them in the water.

Seals

There are three different types of seals in the Delaware Bay: Gray Seals, Harp Seals, and Harbor Seals. The Delaware Bay remains a popular site for seals tomblog1.jpg migrate during the winter. The most popular time to see seals along the Delaware Bay is during the colder months. Seals usually come out of the water to rest after they have eaten. If you catch sight of one of these amazing mammals, contact Marine Education, Research and Rehabilitation at 302-228-5029. 

Gray Seals: These seals can grow to be up to 10 feet long and 800 pounds! They are gray in color, although pups have white fur for the first three weeks of their lives.

Harp Seals: Adults range between 5 to 6 feet and can weigh up to 300 pounds. They eat small fish and migrate towards the arctic during the summer months.

Harbor Seals: Adults are about 6 feet and weigh over 200 pounds. They are blue-grey in color. These seals love to be on land, and will typically give birth to baby seals during the spring and summer months.

The most popular times to see dolphins are during the spring and summer months. They are gray in color and easy to spot from the deck. There are 43 species of dolphins that are recognized. In the Delaware Bay, we typically see 8 species of dolphins including the Atlantic Bottlenose, Striped, and Atlantic White-Sided.

Dolphins are incredibly friendly, intelligent and can live as long as 60 years! When dolphins sleep, half of their brain stays awake to keep them breathing so they don’t drown? Their diet usually consists of fish, squid, and crustaceans. Generally, mating season is in the spring and result in mothers giving birth to one calf. Each calf stays with their mother for the first three years of its life.

Fun Fact: Dolphins tend to leap out of the water to glance at their surroundings and even follow ships! So be on the lookout next time you’re aboard! 

Whales

There she blows! The Cape May Lewes-Ferry captains have been keeping their eyes peeled for whales in the Delaware Bay. Whales have a very large appetite and prefer smaller fish and krill for their meals and tend to swallow their prey whole. They tend to eat 4% of their body weight, with the smallest species of whales weighing 3,000 pounds that’s a lot of food!
