24.4 Conclusions
Carrying out this work, we for the first time explored distribution of the polychaete
P. kefersteini along the Crimean shoreline and by pseudolitoral depths. In the size
structure of P. kefersteini population inhabiting the pseudolitoral zone 20–35-mm
long worms dominate (75%); with increasing depth they occur more and more
rarely, decreasing to 21% at 1 m and to 1% at 1.5 m depths. For the first time growth
and development of juvenile (0.3–1.45-mm large) P. kefersteini were studied and
the time at which chaetae first arose on the body determined; in particular, forked
chaeta appeared in the individuals with 2–3-segment bodies.
