Who am I?

Oh, you know me. I am the only poisonous snake in St. Mary's County. You are probably scared of me but truly I am a laid back kind of critter. I will definitely bite you if you step on me or try to touch me but otherwise I am not bothered. Because I am so laid back I have a dangerous reputation -- I am well camouflaged and will not warn you when I am about to bite. I'm sorry, it just happens so fast. I get scared. As far as snakes go I am not so big, kinda fat, but usually less than 3 feet long. I can be easily identified by my plain brown triangular shaped head. My body has a pattern of light diamond shapes. April is the month when I and my friends usually come out of hibernation. I ma look for a mate in the spring or the fall. I will incubate my eggs in my body and after a few months will give birth to up to ten babies. Watch out for my babies, they are still poisonous, just as poisonous as the adults. As a young-un I do not look like my parents, I am more grey and have a slightly yellow tipped tail. I can live up to 18 years old.

Where can you find me?

 Look for me in sunny patches in the forest. Watch where you step, I blend in perfectly with the brown leaves of fall. I can be found on the east coast of the United States from Florida to Massachusetts. 

What do I eat?

 I eat things that can fit in my mouth. Since I can't really chew, I have to swallow my prey in one piece. This includes mice, rats, birds, toads, frogs. My babies will eat mostly insects, using their yellow tails to attract their meal.

What might eat me?

 Lots of things, especially when I am young. These include other snakes like kingsnakes and cottonmouths as well as bullfrogs, crows, hawks, opossums, and wild cats.

Cool reasons why I am the critter of the month!

  •  Like all pit vipers my eye slits are vertical. But then, if you can see that you are probably too close.
  • Some would say that I give birth to my babies alive, which I kinda do. I just don't lay my eggs in a nest like most reptiles. I keep them in my body until they hatch.
  • I am the cause of many snakebites but I am rarely fatal.
  • I have heat sensing pits on my head which sense warm blooded critters. Makes it easier to find lunch.
  • Like all reptiles, I am cold-blooded which means I cannot regulate my body temperature.
