Perhaps the most interesting is the archaic, football-sized vampire squid, Vampyroteuthis infernalis. The photophores of myctophids, sergestids and cephalopods emit blue light which can adjust to downwelling light. These deepsea fishes are generally neutrally buoyant, either through swimbladders or their flabby, buoyant tissue. They are generally lethargic, have thin tails, and are mostly made of water. Feeding adaptions among meso- and bathypelagic fish include bioluminescent lures, large mouths, large and flexible teeth, dispensable stomachs.
Many fishes send their eggs and larvae to the surface, or they exhibit parental care.
One of the most important and unique features of Monterey Bay is that deep midwater habitats are very close to shore. This increases the ability of scientists from many institutions to sample, observe and study the organisms in this habitat and to provide information on the links of these assemblages to organisms and processes in nearshore habitats. However, major fisheries for the hake or Pacific whiting, Merluccius productus , may could affect trophic interactions in this zone. Literature Cited Next - Section 6.
