You'll just have to take my word on the ID - the photo turned out really dark and it ran off before I could take a better one.
On wet sandy gravel of small creek. Poor shot but markings look like this particular Lycosid wolf spider.
I was passing by Humber lakeshore trails and I spotted this spider. Its brown greyish in colour.
This little black spider had an orange dot on his lower back with two white dots under it.
Arachnids are a class (Arachnida) of joint-legged invertebrate animals in the subphylum Chelicerata. All arachnids have eight legs, although the front pair of legs in some species has converted to a sensory function, while in other species, different appendages can grow large enough to take on the appearance of extra pairs of legs. The term is derived from the Greek word ἀράχνη (aráchnē), meaning "spider".
