What can eels be used for?
EELS, the study of energy-loss due to inelastic scattering of electrons can in principle be used to measure atomic composition, chemical bonding, valence and conduction band electronic properties and surface properties.
Is eel good for the environment?

Why should we care about eels?
Eels used to represent more than 50 percent of fish biomass in some European freshwater environments, and are a significant participant in the food web. Due to eels’ multiple interactions with other components of aquatic ecosystems, they are considered to be important to preserving a balanced ecology.
Is eel blood toxic?
Eel blood is poisonous to humans and other mammals, but both cooking and the digestive process destroy the toxic protein. The toxin derived from eel blood serum was used by Charles Richet in his Nobel Prize-winning research, in which Richer discovered anaphylaxis by injecting it into dogs and observing the effect.

Do eels bite?
In fact, moray eel bites are infamously painful and can cause extensive bleeding. This is because they have teeth that jut backwards so that prey cannot easily escape.

So as global fisheries have banned the capture of eels to protect populations — Japan did so after the 2011 tsunami — consumers have turned to American eels. European eels are also critically endangered.
Do eels have electricity?
