Here is the Alaskan Whipneck:
The Alaskan Whipneck is an Elasmosaur belonging to the group known as the Anguillosaurids. It is a top predator in the Arctic Alaskan seas and is one of the biggest of all Anguillosaurids, commonly reaching 33 feet in length with record specimens at 37 feet, second only to the 42 foot Siberian Whipneck. Unlike some other Anguillosaurs, the Alaskan Whipneck does not have a venomous bite. It is a fast swimmer, propelling itself with its powerful tail.
