'In teeming numbers the eels move through this vibrant world of water. Arriving during the rainy season when the remnant-lakes swell and the volcanic plain swells like a colander in a tub, the eels leave the salt water, summoned to the freshwater by a baffling endocrinal change that compels them landward to furlough as another kind of fish for a while.'
