Net Casting Spider
This Net Casting Spider - Deinopsis sp, is quite an incredible Spider. They are also known as Ogre-Faced Spider for it huge eyes and ugliness. It got its name from the net made by its webs, which it then hold while hanging upside down waiting for its prey to pass by below at night time. When its prey comes within range, it then cast its net to catch the prey.
Check out this video footage of how they built their net and use it to catch their prey :

Although not as clear, it does show the spider's speed when handling an in-flight insect. Posted 9 years ago
The BBC video really show the whole process, but don't be surprised a lot of their footages are not in the 'wild' but 'recreated' in certain conditions. Posted 9 years ago
