Appearance:
  • Spiders have 8 legs - when they move, there are always 4 of the 8 legs on the surface.
  • There are no muscles in their limbs, they move using hydraulic power.

​
Webs
  • Not all spiders spin webs - some wait for their prey to approach them or they hunt and catch it. 
  • The spider's silk is extremely strong. It is considered to be five times stronger than a strand of steel that is the same thickness.
  • When a spider is going to make a new web, it rolls the old one up into a ball, and some species will eat it.  
  • The web is liquid until it comes into contact with the air.
  • There are 7 different types of silk.  Some silk has special glue to make it sticky to catch insects.  Other silk is not sticky.
  • On average, it takes a spider about 1 hour to spin a web.
  • Abandoned spiders' webs are called 'cobwebs'. 
  • Hummingbirds use small sticks and the silk from a spider's web to weave a nest for themselves.
  • Cannot fly, but sometimes they sail through the air on a line of silk - known as 'ballooning'.
  • The silk contained Vitamin K, which helps to prevent bleeding and, in the past, people put the webs on their wounds to help stop bleeding.
