Abstract

The purpose of the present study was to evaluate the morphometrics of three harvested cephalopods, Sepioteuthis lessoniana, Sepia officinalis and Uroteuthis sp. found in northern sea of Aceh Province, Indonesia. Sampling was conducted for six months from July to December 2012 in one week interval. A total of 318 cephalopods; 139 Sepioteuthis lessoniana, 139 Uroteuthis sp. and 40 Sepia officinalis were analyzed for morphometric study and 13 anatomical characters were measured to the nearest 0.01 mm using a digital calipers. Morphometric measurements were significantly different between the different species of cephalopods (ANOVA, p<0.05). S. officinalis differed in six morphological characters (head length, head width, tentacles length, gladius width, rancis width and length) from the squid species. Fin width and length were significantly greater in S. lessoniana than in S. officinalis and Uroteuthis sp. On the other hand, Uroteuthis sp. had significantly greater mantle lengths, standard lengths and gladius lengths than the other two cephalopod species (Duncan Test, p<0.05). However, fin width was similar between S. lessoniana and Uroteuthis sp., while eye diameter was similar between S. officinalis and Uroteuthis sp. A Discriminant Function Analysis scatter plot successfully discriminated the three species indicating significant differences in morphological variation. This analysis also indicates that morphometrically, S. lessoniana and S. officinalis are more similar to each other despite being in different orders.
