Chessie the manatee was spotted in the Chesapeake Bay after about 10 years without a sighting.
The manatee was spotted in Calvert County, Md. on Tuesday when he came to the surface to take a breath, according to the .U.S. Geological Survey. He was last sighted after he swam through the Virginia Great Bridge Locks on Aug. 30, 2001.
The manatees identity was confirmed by Cathy Beck, a USGS biologist who compared photos take of Chessie this week with photos in the USGS database. The manatee sighted this week has the same long, gray scar on his left side as Chessie.
Chessie was first found in the Chesapeake Bay in the fall 1994, when the weather was cooling and scientists became concerned that the manatee would be affected by the cold water, the USGS stated. Authorities rescued Chessie from the bay and placed him in an aquarium for several days before flying him back to Florida and releasing him. Researchers also tagged the manatee.
Scientists aren't planning on removing Chessie from the bay because the water is still warm.
