「Elucidation of species diversity」
More
than 34,000 living species of fishes are known from the world. The species number of fishes continues to increase and 300
to 500 new species of fishes are described
every
year.
This
continued describing
of
many new species indicates that the diversity of fishes
is
still not well understood. Therefore,
it is necessary to research fish species diversity based on
morphology.
