Description 165-170
A total of 1279 of the corallivorous gastropod Drupella cornus (Roding
1798) from the coral reefs in the Gulf of Aqaba, Red Sea,
were studied for age, growth and shell morphometric determinations. The results
show the life span to be seven years. The mean observed lengths of the seven
age cohorts range from 6.4 to 36.3 mm. Theoretically, using Von Bertalanffy's
and Richard's growth formula, the maximum length of this snail may reach 48.0
and 49.0 mm respectively. The annual increase in length is more for young
snails (20.0 mm) than older ones. Shell and dry body weights averaged 1335 and
33 mg, respectively. The relationships of the shell length to shell and dry
body weights are curvilinear. However, the relationships of the shell length to
shell width, aperture length , aperture width are linear. The relative
coefficient of condition (Kn) was higher for young snails (1.45) than older
ones (1.01). The analysis of Drupella cornus population and shell
morphometrics presented in this study supports the view that morphological
differences among species of Drupella are enough to classify these
species.
