A survey was conducted in most
water bodies around Mosul area (rivers, streams and pools) to identify
the existing types of fresh water snails in the studied area. Five major
species were recognized and described in details (Physa acuta,
Lymnaea auricularia, Melanopsis praemorsa, Melanopsis nodosa and
Theodoxus jordani). There were major differences between the
morphology of the five species found as well as their co- occurrence;
mainly Physa and Lymnaea inhabit the same sites while Melanopsis were
found to be restricted to mountain spring waters (stenotherm water).
This may be due to thermal acclimation and their shell of different
kinds, smooth, nodulated and costulated.The present study was supported
by photographs of shells and life specimens. |
