Silk-like secretion from tarantula feet

Most spiders rely on their tiny claws and hairy feet to scurry up walls and cling to ceilings, but it seems that heavier spiders need an extra bit of sticking power. Researchers have found that tarantulas secrete gluey silk from their feet.

The discovery was made accidentally, by researchers at the Max Planck Institute for Developmental Biology in Tübingen, Germany.
