The gills of this eel are contained in a large cavity on either 
side of the head, and do not communicate with each other. The 
fish distends this receptacle with air taken in by its mouth; it 
appears to be able to respire directly from the atmosphere, or by 
means of the air contained in the water. On holding its small gill 
opening firmly closed, it takes in air by its mouth ; should its 
mouth be held closed, it struggles until its head is released, so as to 
be able to respire. If the gills are exposed by cutting away the 
gill membrane, and it is placed in water, it slowly moves its branchia, 
and appears to feel no inconvenience in being unable to obtain 
air direct through its mouth.
