The Black Widow Spider is one of the spider from the United States that is considered dangerous. There are only two other species, the Brown Recluse and the Hobo spider that are also considered dangerous. The Black widow spider is identified by the female being solid black in color with a red hour glass on the belly. She can have a red marking or hour glass on her back as well. Black Widow Spiders are not aggressive and rarley bite unless in self defense.

Black Widow Spiders are one of the easiest spiders to identify. They have a unique shape and the red hour glass is a positive identifier. If bitten by a Black Widow you should immediately go to the hospital. Quick care can really save a lot of pain and possibly prevent death.
These are some photographs of slugs I took. Slug are similar to snails except they do not have a hard shell. Slugs must remain moist or they will die. I took these macro photographs of slugs using a Canon 5D Mark II and a Sigma 180mm lens. These Slug photographs are the only ones I have taken of this species.
These are some Green Anole macro photographs. Green Anoles are common in the Southern United States. These lizard can change color from light brown to bright green. Green Anole hunt and eat insects. These lizards are good at keeping pest away. The lizards are shy and will attempt to run away. If they are captured they will attempt to bite. The bite is not serious but may draw blood.
These small lizards are native to the United States. They can be found in the Eastern Texas to the East Coast. Brown Anoles are invasive and were brought over by accident from Cuba. Even though the Anole in these photographs is brown in color, it is a Green Anole that is currently in brown phase.
These is a pretty jumping spider called a Dimorphic Jumping Spider. I have only seen one of this species. I took these macro photographs with a Canon 5d Mark II using a Canon MP-E 65mm lens.
I found this Hammerhead flatworm on mother's day. I have never seen of of heard of these things. Hammerhead flatworms are not dangerous but they are pest and eat earth worms which are beneficial to your garden.
