Animal builders: spiders' webs and silk, sentence 8
For its weight, some spider silk is stronger than steel and very stretchy, because its proteins are lined up in a special way; Darwin's bark spider in Madagascar spins webs across rivers up to about 25 metres wide.
Who acts: spider silk, bark spider · What happens: be, line up, spin · To what, where: proteins, webs, rivers
