Fascinating Facts About Fish on Earth

Fish are creatures closely connected to life… And now, let’s explore some interesting facts about these species. You’ll be amazed to see them.

Fish can still drown

You often hear about land creatures accidentally falling into the water and drowning if they can’t swim, right? But underwater fish can still drown. It’s true, fish also need oxygen to breathe when living in a water environment. If there isn’t enough dissolved oxygen in the water or if they live in a polluted environment, fish can still suffocate like any other creature.

Fish have taste buds all over their bodies

For humans and some other animals, taste buds are located only on the tongue. However, for fish, taste buds are present all over their bodies. This has been proven, as fish can sense flavors in their surroundings even when their mouths are closed. It’s a fascinating fact that not many people know, isn’t it?

Fish can swim upside down

You might see a swimmer doing the backstroke or a stingray swimming upside down for fun in the water. Similarly, some fish have the ability to swim upside down. Many people think they do it because they’re about to die and no longer have enough strength to swim. But in reality, it’s just a behavior of those fish species.

They have a unique sensory organ

For marine fish like whales, dolphins, and others, they have a very special sensory organ similar to radar systems used for navigation. This enables them to move in dark, murky water and deep, dim areas below the sea. With this ability, these fish can migrate to different areas without fear of getting lost.

Sex change is possible

Some fish species have the ability to change their current gender during their lifetime. It’s a quite fascinating discovery. How is it possible for a female fish to live for a while and then transform into a male fish, and vice versa? But that’s the truth for certain fish species such as wrasses, clownfish, parrotfish, or seahorses.

They swim continuously without rest

To be able to float on the water’s surface, sharks and some other fish species lack a swim bladder. Consequently, these fish have to swim continuously or take rests at the bottom to avoid losing energy and experiencing oxygen deprivation.

Toxicity can be lethal to humans

You’ve probably heard of the pufferfish. It’s an extremely dangerous fish because it contains toxins in its body that can be deadly to humans. Many people still use pufferfish as food; however, if not prepared carefully, it can be harmful to consumers. Did you know that the venom of a pufferfish can kill up to 30 people? That’s why you should be cautious when deciding to consume this type of fish.

These are just a few intriguing facts about fish. They demonstrate the diversity and wonder of the aquatic world. Next time you encounter a fish, remember the incredible qualities and characteristics they possess.
