I sometimes read threads here where people talk about seeing (for example) Brown Recluse spiders in their house. I’m partly amazed that you can have things living in your house that can cause serious injury, and partly happy that I need never worry about that happening here in Britain. Then I thought - hey we hardly have ANY venemous creepy crawlies in this country! Millions of years ago, when the continents where seperating, how did we get short changed?
America has the black widow, brown recluse, rattle snake. South America has the Brazilian Wandering spider, and numerous dangerous snakes. Australia seems to have got more than its fair share of deadly critters - Great White shark, Sydney Funnel Web spider, Redback spider, Box Jellyfish, Kind Brown snake. All extremely dangerous.
What did Britain get? The adder. The only venemous animal. All of our spiders are harmless. We have no dangerous jellyfish or sharks. Its not fair! Even parts of neighbouring Europe has venemous creatures. Is it the colder climate? Did all the really tough creatures emigrate? Or should I just be happy no-one has carried a mating pair of Brown Recluses over in their luggage?
