Top 10 Common Misconceptions About Biology
Let's be honest we all heard this "fact" coming from your grandmother's tales. Common sense will assure you that humans don't swallow several spiders during their sleep. Even a spider would have that kind of common sense to not kill themselves between a human's esophagus.
It's common for movies and other pieces of media to depict wolves howling at the full moon, but in real life the phases of the moon is not connected to the wolves howling. Howls are often communicated as a call for a group, a sign of affection, or when stepping in unknown territory.

If you watched movies, you typically heard of the iconic "eagle" sound screeching. Many of us unconsciously assume the cry is associated with the eagle. Nope, it's actually a red tailed hawk. The screeches of the eagle are actually weaker than you think; it comes off more of a high-pitched chirp.

It's commonly thought that flies live for a few hours, or several days. However, it's much longer than you think. The average housefly can last for two weeks to up to a whole month. Mayflies are one of the few species that can last a day, but some species live even shorter lifespans than that.
It's been commonly believed that male lions rely on females on doing the hunting. However, they do hunt occasionally and they mostly succeed on it, but they're more inclined to patrolling their territory.
