Common Misconceptions

Misconception: All snakes are venomous

• Not all snakes have venom glands
• Non-venomous snakes can still bite and cause injury
• Many venomous snakes have non-lethal venom and pose no serious threat to humans

One of the most common misconceptions about snakes is that all of them are venomous. While it is true that some snakes, such as cobras and vipers, are venomous, many others do not possess venom glands. In fact, approximately 60% of snake species are non-venomous. Additionally, it’s important to note that while non-venomous snakes may not inject venom, they can still bite and cause injury. However, it is worth mentioning that even among venomous snakes, many have venom that is not lethal to humans. Understanding the diversity and characteristics of snakes can help dispel this misconception.

Misconception: Bats are blind

• Bats can see, although their vision is adapted for low-light conditions
• Echolocation is the primary navigational tool for many bat species
• Blindness is a rare condition among bat populations

Contrary to what many believe, bats are not blind creatures. While their vision is not as developed as some other mammals, including humans, bats possess eyes and are capable of seeing. However, due to their nocturnal lifestyle, their vision is adapted for navigating in low-light conditions. What truly sets bats apart is their use of echolocation, a remarkable ability to emit high-frequency sounds and interpret the returning echoes to navigate and locate prey. It is worth emphasizing that blindness is an uncommon condition among bat populations, and most bats have functional vision combined with their echolocation skills.

Misconception: Goldfish have a three-second memory

• Goldfish have the ability to remember things for months
• They possess good associative memories and can be trained
• Studies have shown goldfish can recognize their owners

Many people believe that goldfish have an incredibly short memory span, lasting only three seconds. However, scientific research has debunked this misconception. Goldfish possess relatively good memories and are capable of remembering things for several months. They have been shown to remember cues related to food, navigate mazes, and respond to conditioning and training. In fact, studies have even demonstrated that goldfish can recognize their owners, which further supports their ability to form memories and associations.

Misconception: Bulls are enraged by the color red

• Bulls are colorblind and do not specifically react to the color red
• Movement and provocation trigger bull’s aggressive behavior
• The red color used in bullfighting is more for the audience’s visual effect

Contrary to popular belief, bulls are not enraged by the color red. In fact, bulls are colorblind to certain colors, including red. The reason red is often associated with bullfighting is solely for the visual effect for the audience. However, what triggers aggressive behavior in bulls is not the color, but rather movement and provocation. The matadors’ cape movements stimulate the bull’s aggression in the traditional Spanish spectacle. Understanding this can help dispel the misconception and bring about a more accurate understanding of bulls’ behaviors and reactions.

Misconception: Lightning never strikes the same place twice

• Lightning can strike the same location multiple times
• Tall structures, such as skyscrapers or towers, are often struck repeatedly
• The idea may have originated from the notion that lightning seeks the “easiest” path

It is often believed that lightning never strikes the same place twice. However, this is a common misconception. Lightning can, and quite frequently does, strike the same location multiple times. Tall structures, such as skyscrapers or towers, are particularly vulnerable and often experience repeated lightning strikes. This misconception may have originated from the idea that lightning seeks the “easiest” path to the ground during a thunderstorm. While lightning can indeed establish a path of ionized air, known as a “channel,” it certainly can strike the same spot multiple times.
