TARANTULAS shoot silk from "spigots" in their feet to climb slippery surfaces, a new study says, according to a National Geographic News report.
The delicate arachnids often use silk much like Spider-Man does when wall-crawling - to stick to surfaces and stay firmly attached, even when the ground is shaky, the research confirmed.
The silk-slinging theory was first put forth in 2006, but scientists have been divided on whether tarantulas shoot silk from their feet, or if they grab silk from their spinnerets - silk-producing organs - and use that as a glue.
