Answer 1

Spider silk is the strongest of all natural and man-made fibres -- much stronger than silk from the delicate webs spun by silkworms. It is even stronger than steel: the dragline of a European garden spider (Araneus diadematus), for example, can support a weight of 0.5 g without snapping, whereas a steel strand of similar thickness will snap under the strain of just 0.25 g. Golden orb-web spiders in the genus Nephila are believed to produce the strongest of all spider silks. Large orb-web spiders sometimes catch small birds in their webs.

Answer 2

It depends on the kind of spider and the kind of silk. Spiders
have several kinds of silk glands that produce different silks
with different strengths. The silk of the supporting framework
of an orb web is stronger than that of the preycatching part of
the web. The silk of the black widow spider is stronger than
that of many other kinds of spiders. It also depends on whether you are talking about a single thread spun by a single silk gland or about the silk as it is laid down by the spider,
which is often formed of threads from several glands combined. The silk of the golden silk spider, Nephila, is said
to be used for catching fish by natives of New Guinea. They
make a hoop of vine or tree branch and pick up "several" webs on this hoop. This method is said to be capable of
catching fish of up to a pound weight.

Answer 3

Some of the large nephilas are called bird-eating spiders because they catch small birds in their orb webs. They will also catch microbats that fail to avoid them. The orb can be a metre or more in diameter with the suspension lines some metres long. Big ones are found in Papua New Guinea and north Queensland.
