Spider silk spinning field, the spinneret apparatus of an adult "Araneus diadematus" (garden cross spider) consists of the glands shown below. Similar multiple gland architecture exists in the black widow spider. In order to artificially synthesise spider silk into fibres, there are two broad areas that must be covered. These are synthesis of the feedstock (the unspun silk dope in spiders), and synthesis of the spinning conditions (the funnel, valve, tapering duct, and spigot). There have been a number of different approaches. The molecular structure of unspun silk is both complex and extremely long. Though this endows the silk fibres with their
European bass commercial fish widely cultured in the Mediterranean. The most important farming countries are Greece, Turkey, Italy, Spain, Croatia, and Egypt. Annual production was more than 120,000 tonnes in 2010. European bass is also known as lavraki (Greek: λαβράκι]), levrak (Hebrew: לברק), levrek or bayağı levrek (Turkish). loubina (Spanish) and loup de mer (French).
