"one thing led to another"

Paul Sieswerda spent a 40 year career as Curator at both the New England and New York Aquariums.  He rescued stranded animals along the New England coast while at the Aquarium in Boston (he and his wife, Candi, raised a baby seal in their home), and worked to rehabilitate stranded animals in NY,  Now he is tracking seals, dolphins, and whales in the waters of New York.   He is Lead Naturalist aboard the American Princess where he heads a Citizen Science project, Gotham Whale, to track marine mammals close to New York City.

 Whale Tails and Skyscrapers

A young humpback whale dives "within cell phone range" and with the skyline of Manhattan in the background.  How cool is that? Humpbacks are in the hood!!


Gotham Whale enlists citizens to share images they have taken while whale watching aboard the C/V American Princess. These images document behaviors and markings that our researchers record in our database.

For instance, see the exceptional photograph of the lunge feeding of a humpback in the slide show above taken by Philip Ng, Knightmare Photography. This photo not only is a dramatic image of the whale behavior known as lunge feeding, but it clearly shows the fish on which the humpback is feeding.  The image is so clear that the species of fish, Brevoortia tyrannus, or Atlantic Menhaden, can be identified. The size of these fish being consumed dispels the common notion that baleen whales only eat tiny fish and krill.
