Table 2 Most abundant lipid species within each lipid class, categorized as glycerophospholipids and sphingolipids, identified in the arm muscle of Octopus vulgaris collected from three distinct landing sites along the Iberian Atlantic coast: Ria de Arousa (RAr), Peniche (Pe), and Santa Luzia (SL). When the most abundant lipid species differed among locations, the corresponding site is indicated in parentheses
