Tropical Red Sea fish colonizes the Mediterranean Of the many
exotic fish living in the Red Sea, one of the most unique and
well-known is the cornetfish (Fistularia commersoni). This
meter-long silvery fish resembles a long, thin flute, with a
rigid, pipe-like mouth. Until recently, anyone who wanted to see
cornetfish had to go south, to the Red Sea. In the past decade,
however, this fish has begun to appear in the Mediterranean Sea,
where it is multiplying rapidly. Dr. Daniel Golani of the
Department of Evolution, Systematics and Ecology at Hebrew
University in Jerusalem has been following the integration of
the cornetfish in its new surroundings. Golani joined forces
with researchers from Greece and Italy in order to understand
how invading species integrate into their new environments. The
findings of this study were published recently in "Biology
Letters." Here, Golani describes how the cornetfish spread in
the Mediterranean - part of the broader phenomenon of various
species migrating from the Red Sea to
