Blake (Ship); Marine animals -- Atlantic Ocean; Marine sediments; Ocean. Fig. 195. — Sternoptyx diaphana a haul in mid-ocean, is entirely at a loss to know where his cap- tures have been made. If he has taken a flounder from a haul in 800 fathoms, or finds a macruroid, a brotuloid, a berycoid, a synodontoid, or a nemichthyoid in a net which has been below the two-thousand- fathom line, he feels tolerably sure that he has brought it up from the bottom. But who shall say where those which like Argyropelecus, Sternoptyx (Fig. 195), or Cyclothone (Fig. 196), having al- lies among the pela- gic fishes in the same net, have come from ? They may have come from the bottom, or they may have become entangled in the meshes of the trawl when but a few fathoms below the surface, in its ascent or descent. Many of the deep-sea fishes undoubtedly lead a most active life in spite of their cartilaginous bones and feeble muscular system, being kept ef&cient perhaps by the enormous pressure under which they live. The abso- lute calm of the abyssal re- gions may be the cause of the extraordinary development of some of the tactile or other Fig. 196. —Cyclothone lusca. \- (U. S. F.

The acces- sory eyes may perform the part of bull's-eyes, thus constituting, according to Dr. Gunther, " a very deadly trap for prey, one moment shining that it might attract the curiosity of some sim- ple fish ; then extinguished, the simple fish would fall an easy ; Some of the long filamentous organs are phosphores- cent, while others ar
