Octopus vulgaris, often called the common octopus, represents a cephalopod of the order of octopods; it's genuinely appreciated by humans and has long been a part of the coastal population's diet. Besides, it plays an interesting economic role in the area. Therefore, it seems essential to identify its populations and preserve this marine biological heritage. The objective of our study is the identification and morphometric characterization of the common octopus on the west Algerian coast, precisely in the region of Ghazaouet, Beni Saf, Oran and Arzew on 50 individuals. Seven morphological characteristics were measured using a tape, according to the proposed protocol by Roper and Voss (1983). To highlight the diverse and similar points of the sampled individuals, the study relied on the statistical analysis of the values of the measurements of the morphometric characters. It has revealed a significant variation in the morphometric characteristics of the octopus vulgaris on the west coast of Algeria and has supplied us with more information about the biological diversity of our country. It is therefore significant to adopt appropriate strategies to conserve and support this diversity
