If you're ever lucky enough to actually see a snake eel, this is probably all you'll see (a head). This photo, along with the other three other snake eel photos were taken at a place we called the "eel grass", a shallow area about 23 feet deep located at Batangas, Luzon island, Philippines. The spot was named for the characteristic vegetation and sand. All the times I ever saw snake eels were at night; they are reclusive creatures and difficult to find.
This particular eel, along with snake eel #3 below, may be a special type of snake eel called a "crocodile snake eel".
