Male Salticus scenicus

Sorry arachnophobes But this is something I've never seen before the large black horn type things are  Its the large Chelicerae  used for fighting, handling the females amongst other things. 
This one is < 1cm so don't worry about them. and no focus stack on this , it was moving about too fast.
managed a walk in the arboretum this afternoon by myself and without my walker :-)
