Weird Fun Facts about Fishes
Fish is a limbless cold-blooded vertebrate animal with gills and fins living wholly in water. These weird fun fact post is sharing facts about the small as well as large aquatic animals and not about a person who is strange in a specified way. Read and share these facts. You can post your opinions in the comments section, don’t worry, there is a lot to discuss.
1) Can Taste Without Opening Mouth
Did you know fishes can taste without opening their mouth?Just like humans, fishes too have taste buds. That allows them to taste the food. These taste buds are located inside the mouth as well as on the outside body.
2) Catfishes Have Taste Buds on Barbels
Did you know catfishes have taste buds located on their barbels?
The fishes living at the bottom of the water have these barbels (tentacles extended off their heads).
3) Can Suffocate in Water
Did you know fishes can drown (suffocate, actually) in water?Not technically. But, because of suffocation when their gills fail to extract oxygen from the water. As per dictionary the drown means, “die through submersion in and inhalation of water.”
When fishes failed to extract oxygen from the water they suffocate. The suffocation means, “the state or process of dying from being deprived of air or unable to breathe.” Though this is not technically true, but, we can call it this way.
4) Can Get Sunburns
Did you know fishes can get sunburns too?
Weird, more than funny. Though they live underwater they can still get sunburns. Shadow and clear water without a lot of shade makes them vulnerable to sub UV lights causing burns. It’s due to environmental conditions and not because of their will.
5) Can Produce Sunscreen
Some fishes can produce own natural sunscreen to fight the sun rays. According to the study published by, Oregon State University, United States, that, “Ultraviolet-protective compounds, such as mycosporine-like amino acids (MAAs) and related gadusols produced by some bacteria, fungi, algae, and marine invertebrates, are critical for the survival of reef-building corals and other marine organisms exposed to high-solar irradiance. These compounds have also been found in marine fish, where their accumulation is thought to be of dietary or symbiont origin.”
6) Parrotlike Fishes: Parrotfishes
Did you know there is a parrot like known as parrotfish?
It it due to their fused teeth, which bear close resemblance to a bird’s beak. Parrotfish have thick, heavy bodies and large scales.
They are found in tropical waters throughout the world and appear in a wide variety of colors, which may change depending on their sex, status, or maturity. They eat algae and coral.
7) Parrotfishes Are To Much Social
Did you know parrotfishes are highly social and lives in schools of around 40 individuals. The supermale leads these schools. Supermale is an adult breeding male.
8) Sensors to Detect Predetors
Did you know the fishes have special sensors that allow them to detect the predators?
The lateral line is a hydrodynamic receptor system that enables fishes to detect minute water motions generated by conspecifics, predators or prey. The sensory units of the lateral line are the neuromasts which are dispersed over large portions of the body surface.
9) Camouflage Using Countershading
Did you know fishes use countershading camouflage technique to hide from predators?
Countershading is a color pattern where the back or top of an animal is darker-colored, and the belly or underside of the animal is light-colored or white. This helps make an animal less conspicuous to predators. In the water, light comes from above.
So if you look up at a fish from below, you see it against a bright background. A light-colored fish bottom side is harder to see from below than a dark-colored one. Conversely, if you look downward in water, the bottom looks comparatively dark, so a fish with a dark-colored top side is harder to see.
10) Sharks Keep Swimming to Remain Alive
Did you know sharks have to keep swimming to remain alive? All sharks take oxygen from water so they can breathe. But sharks like these ones can’t pump water over their gills. So to stay alive, the sharks have to constantly swim forward. This keeps water filtering through their gills, so they’re always taking in oxygen to breathe.
