This is a vintage scientific illustration of an octopus, likely from a natural history publication. The octopus is depicted head-on, with its eight arms radiating outwards. The arms are long and slender, covered in small, evenly spaced suckers. The body (mantle) is a reddish-brown color, speckled with tiny dots, creating a textured appearance. The head has two prominent, round eyes with dark pupils. The illustration is detailed and precise, characteristic of scientific illustrations of the time. The background is a pale cream color. Above the illustration, the text reads 'Cephalopodes' and 'Pl.7'. Below the illustration, there is text identifying the species as 'Octopus tetracirrhus' and the artist as 'Delle Chiaje'. The illustration is framed by a simple rectangular border.
