Due to the day rolling into evening, Cephalopodae of our bay have got active. Right after getting to know cuttlefish we had a pleasant acquaintance (aquaintance?) with an octopus, that was spending an afternoon at the threshold of it's home at the middle of sponge gardens, in a company of two striped Serranus scriba with yellow tails.
A shell of Venus verrucosa might be seen inside the shelter. Octopuses enjoy collecting and using shells as tiles on the walls of their homes. Finding a living shell makes them even more glad: drilling it with it's rasping tongue, it gets both the dinner either the building materials.
