A manatee was spotted in the Delaware River Tuesday evening, according to multiple reports.

The seven-foot long manatee, spotted north of Philadelphia near Crosswick Creek in Bordentown, was seen by a fisherman, the New Jersey Department of Environmental Protection told the Philadelphia Inquirer.

A conservation officer who was dispatched confirmed the mammal was swimming in the river near the I-295 bridge, state Fish & Wildlife officials said, according to NJ.com.
