I used to believe that when people dissected frogs in school, the frogs were just sleeping. Like if they had an operation, the people would put them back together after the dissection and then the frogs would just go back to living their lives.

I used to believe that The Horse was The Cow's husband, and that it produced chocolate milk.
I used to believe that all the dogs were male and that all the cats were female. I believed this until I saw a male cat and a female dog.
When I was little my dad always used to joke and say "Look! A flock of turtles!" Then he would quickly snatch a chip or a piece of food. I grew up actually thinking that the collective noun for turtles was a 'flock'
I thought that when they raise animals for food they would wait for them to die of old age before we ate them as I figured it would be too mean to kill them..
I used to believe that every squirrel I saw was the same squirrel because when my mom and I saw a squirrel anywhere, my mom would say, "Look, there's your squirrel friend!" And I believed her :-p
When I was little, I used to believe the cause of earthquakes were Gorillas and Monkeys standing on my rooftop shaking the house, kinda like King Kong. After the big '94 earthquake that took place in Northridge, California, I ran out my house looking for the monkeys, but was very disappointing when I couldn't find any. It wasn't until years later when I learned about science and seismic waves that I understood the real cause of earthquakes.
I thought that snakes were just a tail and a head like they looked like i.e I didn't know they had any internal organs in their bodies. Later when I learned that lizards can drop thier tails I thought that snakes could drop their whole bodies and would just be a head until it grew back!
I used to believe that all cats were female and all dogs were male, even though my friend had a female dog and I eventually got a male cat.

When I was a little kid, I used to believe that worms turned into moths like caterpillars turn into butterflies.
My dad took me to see Arachnophobia when I was about 7, I've been terrified of spiders ever since. If I saw one in my room and it got away before it was killed, I'd throw a fit and not go to sleep- my mom told me that spiders didn't like crawling on beds so I was safe there- something about they like hard surfaces, it's easier for them to walk- seemed believable enough =) I seriously believed that until I was about 27 and my mom admitted to lying to me...lies, all lies!!! I kinda wish I still believed that though- I freaking hate spiders!
As an extension of the "salt on a birds tail you can catch it" myth, my Dad used to tell us that every Easter he would wait up to catch the Easter Bunny by putting salt on his tail. The only logic that fit was that since the Easter Bunny lays eggs for Easter (another thing he told us) the salt on the tail must apply. As an adult I actually had to look it up to see if this was a true myth or something he made up on his own.
When I was little I ALWAYS slept on my side and pressed my ear into my pillow to protect my ear from earwigs crawling in it. On the other ear I placed a stuffed animal or covered my head with the blankets.
I thought for a long time that beaver and badger are the same animal
I used to wonder why Great White sharks were called that as what was so great about them if they eat people (this was before I knew great could also just mean big.

I thought that spiderwebs and cobwebs were two different things: apiderwebs were made by spiders, but cobwebs just magically appeared!

I thought that rat poison is only poisonous to rats and harmless to humans and other animals (fortunately I never acted on this)
I used to believe tigers were all female,and lions were all males. When they breeded and had a cub; if it were female, it was a tiger and if it were male it was a lion.
When I was young (about 4/5), I used to believe you could hatch an egg by putting it in a towel and keeping it warm. I came up with it after talking about it with my best friend at the time “Thomas”. Both of us took an chickens egg out of the kitchen and tried to hatch it. We stuffed them in a bunch of towels and took the eggs everywhere. And I literally mean everywhere. We brought the eggs with us in a bag stuffed in towels to: school, daycare, when we were playing outside and so on. We checked our eggs everyday to see if they were already hatching and to see if they had any cracks and/or tears. We also replenished the towels everyday so they would stay clean, but before we would change the towels, we would warm the new ones up so the egg wasn’t going to be wrapped in cold towels. After a week or so we started to notice nothing was happening, and we were wondering why the eggs weren’t hatching. We were convinced there was something wrong with the eggs, so we took our mom’s to the supermarket to buy us some new eggs and tried again. A week later the eggs still didn’t hatch and our moms told us that eggs out of the supermarket wouldn’t hatch because they sort the eggs that contain embryo’s out of the packages and throw them away. After that we became mad at our mom’s for letting us take the eggs everywhere and why they made us take all the effort of trying to hatch them while they knew they wouldn’t hatch. For years I was convinced I could make an egg hatch by putting it in towels if I could just get my hands on a “good” egg.
