2024年10月18日 · And the short answer to your question is spiders do innately know how to build their webs, but to explain how and to provide some insights into the amazing variation in these silky structures across species, his professor of evolutionary biology and genetics at the University of Nottingham and spider specialist Sara Goodacre.

Find out how web-spinning spiders do what they do and learn about the impressive, multipurpose material they use to catch their dinner. Spiders make their webs from silk, a natural fibre made of protein.

2023年9月3日 · To construct a web, spiders use a natural liquid protein that is produced in their silk glands. When this protein is released through the spinnerets, it solidifies upon contact with the air, forming the thin, strong strands that make up the web.
