Gaghiel

Gaghiel (Hebrew: גגיאל) is the Sixth Angel, resembling a giant prehistoric fish-like creature or possibly a strange variety of mosasaur, and the only aquatic Angel.

Gaghiel is the only angel truly adapted for aquatic environments alone, as opposed to Sachiel, who was amphibious. Unlike most Angels, it has a massive mouth with multiple rows of teeth, like a shark. The Angel's core is located in the back of its throat, behind its tongue. Gaghiel also has a small bony "face" plate similar to that of Sachiel located on its dorsal surface.

Gaghiel's "body core" alone, from the tip of its jaws to the base of its tail, appears to be slightly larger than a Nimitz-class aircraft carrier, which is itself 317 meters long (well over 1,040 feet).
