Guinness world records has listed Brazilian Wandering Spider as the most poisonous spider in the world. They wander the floor at night rather maintaining a web or residing in a lair. During the day time, they will hide under the fallen logs, termite mounds, under the rocks and even in a banana plant.
One of the deadliest spiders in the world has been captured on camera in the wild in Britain - outside a garden shed in Goucester. Les Fryer, 71, saw a highly poisonous funnel-web - the first time the species has ever been found in Britain.
