What's in the Water: The Sea Squirt

Manhattan, as seen from a boat in the middle of New York Harbor. A third of New York City's area is not land, but water. Its coast is 520 miles long.

For this membership drive, we'll feature a brisk deep dive on a different species found in New York City waterways, and the ecological issues that impact them. To wrap up the series, Ann Fraioli, director of education at Billion Oyster Project, shares her knowledge of the Sea Squirt.
