Gymnotus

Electricians are now examining the animal source of electricity in the electric eel (Gymnotus electricus); zoologists are still searching for the solution of the problem of the generation of eels, of which no more is known than that the young eels are not born alive; and numerous fishing societies are now studying the important question of raising eels in ponds, lakes, etc., that are not connected with the sea.

I was as exhausted as a _Gymnotus_ that has parted with all its electricity.

In the case of the _Torpedo_ [a fish belonging to the family of Electric Rings] this identity has been fully proved, but in the case of the _Gymnotus_ the proof has not been quite complete, and

In the Gymnotus and torpedo they no doubt serve as powerful means of defence, and perhaps for securing prey; yet in the ray, as observed by Matteucci, an analogous organ in the tail manifests but little electricity, even when the animal is greatly irritated; so little, that it can hardly be of any use for the above purposes.

Although its structure is throughout as complex and perfect as that of the electric organ in _Gymnotus_ or _Torpedo_, its smaller size does not admit of its generating a sufficient amount of electricity to yield a discharge that can be felt by the hand.

On the other hand, seeing that electric organs when of larger size, as in the _Gymnotus_ and _Torpedo_, are of obvious use to their possessors, the facts of the case, so far as the skate is concerned, assuredly do appear to sanction the doctrine of "prophetic germs."

Electric organs are known to occur in several widely different kinds of fish -- such as the _Gymnotus_ and _Torpedo_.

It is not only the torpedo or the _Gymnotus electricus_ that can send us messages from the ocean.
