| Current
Research Interests |
| I
am interested in the ear structure of deep-sea fishes (please
see "Deep-Sea Fishes").
My current research project is a comparative study of the inner
ear morphology and ultrastructure in deep-sea gadiform fishes,
specifically the families Macrouridae and Moridae. For the past
two years I have also supervised an undergraduate student, Bradley
Buran, whose project also examined the structure of the ear
in deep sea fishes. These fishes are the most abundant species
in the benthopelagic fauna between 1,000 and 5,000 m. At these
depths, there is little or no light, food is scarce, and there
are considerable distances between individual animals. Thus,
we hypothesize that these fishes have evolved acoustic communication
and possibly auditory specializations to enhance detection of
communication sounds.
The main purpose of my study is to find out the structural
relationships between the otolith, otolithic membrane and
sensory epithelia in the saccule and lagena of these deep-sea
fishes. By analyzing the difference in the inner ear structure
of fishes from different depths and habitats, we may get some
insight into the evolution and adaptations of these deep-sea
fish auditory systems.
