What happened to the dolphins stuck in an Inwood canal?

Two dolphins that waded into Joseph Sanford Jr. Channel near the Inwood Marina on June 23 had two different outcomes as an adult female dolphin found to be malnourished and extremely dehydrated had to euthanized on Sunday.

The scene unfolded in the shallow canal at the end of Maple Road, the Inwood Fire Department posted on Facebook. They were on the scene along with officials from the New York Marine Rescue Center and the state Department of Environmental Conservation.

The calf returned to pen water. Its gender and age was unknown. The adult had become stranded on a mud flat as the tide receded as rescuers tried to move the dolphins out of the creek.

The dolphins were first seen on June 19 in Jamaica Bay near the Cross Bay Veterans Memorial Bridge and the South Channel Bridge that is between Broad Channel and the Rockaways.

Both dolphins were identified as Risso’s dolphins, which are also called gray dolphins.

There are roughly 60,000 Risso’s dolphins around the continental shelf of the United States. Typically, they grow to 8.5 to 13 feet and an adult usually weighs 850 pounds.
