tibly drawn toward them as do the moths that
fly toward the lamp, and the birds of the sea that beat against the
lighthouse.

None of the lights of the earth can compare with those of this abyssal
world. All artificial fires pale before the varieties of its organic
brilliance.

The living branches of polyps, the eyes of the animals, even the mud
sown with brilliant points, emit phosphoric shafts like sparks whose
splendors incessantly vanish and reappear. And these lights pass
through many gradations of colors:--violet, purple, orange, blue, and
especially green. On perceiving a victim nearby, the gigantic
cuttle-fishes become illuminated like livid suns, moving their arms
with death-dealing strokes.

All the abyssal beings have their organs of sight enormously developed
in order to catch even the weakest rays of light. Many have enormous,
protruding eyes. Others have them detached from the body at the end of
two cylindrical tentacles like telescopes.

Those that are blind and do not throw out any radiance are compensated
for this inferiority by the development of the tactile organs. Their
antennae and swimming organs are immeasurably prolonged in the
darkness. The filaments of their body, long hairs rich in nerve
terminals, can distinguish instantaneously the appetizing prey, or the
enemy lying in wait.

The abyssal deeps have two floors or roofs. In the highest, is the
so-called neritic zone,--the oceanic surface, diaphanous and luminous,
far from any coast. Next is seen the pelagic zone, much deeper, in
which reside the fishes of incessant motion, capable of living without
reposing on the bottom.

The corpses of the neritic animals and of those that swim between the
two waters are the direct or indirect sustenance of the abyssal fauna.
These beings with weak dental equipment and sluggish speed, badly armed
for the conquest of living prey, nourish themselves with the dropping
of this rain of alimentary material. The great swimmers, supplied with
formidable mandibles and immense and elastic stomachs, prefer the
fortunes of war, the pursuit of living prey, and devour,--as the
carnivorous devour the herbivorous on land,--all the little feeders on
debris and _plancton_. This word of recent scientific invention
presented to Captain Ferragut's mind the most humble and interesting of
the oceanic inhabitants. The _plancton_ is the life that floats in
loose clusters or forming cloud-like groups across the neritic surfa
