Their internal organs are extremely small and only possess a single tube to make the intestines, but also the bodies of these eels do not have any red blood cells. It is this special combination that makes them crystal-clear.

This group of exotic creatures is extremely diverse and abundant, they include 801 species, in 24 orders, 24 families and 156 genera.
