What do spiders use to hunt?
Instead, they hunt by using a sticky ‘capture blob’ of silk on the end of a line, known as a ‘bolas’.

Because of this, they are also called angling or fishing spider.
Are spiders the best hunters?

How do Portia spiders hunt?
While most jumping spiders prey mainly on insects and by active hunting, females of Portia also build webs to catch prey directly. These “capture webs” are funnel-shaped and widest at the top and are about 4,000 cubic centimetres in volume. A Portia often builds her own web on to one of a web-based non-salticid spider.
Do spiders have brains?

The spider’s central nervous system is made up of two relatively simple ganglia, or nerve cell clusters, connected to nerves leading to the spider’s various muscles and sensory systems.
How long does a spider live?
