I've just been cleaning out my rabbit hutch and found a spider that i've never seen before. It's about 8mm long (not including legs). It's shiny black with two small, barely visible, triangles pointing upwards on its back. There are four small pin prick indents surrounding the top triangle. He has a large abdomen, small head. His legs are black and about the same length as his body. Any ideas anyone? He looks really scary!!
