Arachnids

It might seem strange that despite my lifelong fear of spiders I nevertheless find this group of invertebrates among the most interesting of all life-forms, the sheer variety of spiders being mind-boggling. Indeed the average home probably has at the very least a dozen or so species living inside and outside its walls, ranging from the charming Zebra Spiders whom hunt for prey using only their speed and sharp eyes, to the much less welcome House Spiders whom skulk in dark unused corners, only appearing in late summer and autumn in order to breed. I may not love spiders but you can’t deny that they are rather fascinating organisms.
