Deep Creatures

  Directions

Study the instructional material below. Be sure to click on each of the photographs for an enlarged view in a separate window. The larger version is necessary to complete the assignment. It opens in a separate window which can be resized by grabbing the bottom right corner and dragging it. It can also be moved by grabbing the top heading bar and dragging it. Be sure to close the extra window by using the X in IBM, or the close box in MAC when you are finished using them.

  Introduction


The animals of deep pelagic and deep benthic environments are well adapted for living under high pressure in perpetual cold and darkness. They differ from their shallow water relatives in both appearance and behavior. In this lab activity you will study the fishes of the midwaters and deep sea and the invertebrates of the deep sea benthos.

Top  Instruction
