While the world's biggest spiders are mygalomorphs – Theraphosa blondi has a body length of 10 cm (3.9 in) and a leg span of 28 cm (11 in) – some species are less than one millimeter (0.039 in) long. Mygalomorphs are capable of spinning at least slightly adhesive silk, and some build elaborate capture webs that approach a metre in diameter.
