Notes

Very slender, long body with slender, pointed head. Long whip-like tail. Head often slightly darker than rest of body. Colors range from white to blue/grey. Distinguishable by swimming pattern: majority of slender body nearly completely straight with propulsion driven by flexion of terminal ¼ to ½ of body.
