Top 40 fish facts that will make you appreciate fishes more

My best friend usually says there are two ways to love fishes; either by eating them or raising them as pets. I have eaten a lot of fishes but the memory lasts only as long as the taste lingers in my mouth. It was not until I decided to raise a fish as a pet that I began to truly see a lot of interesting things about fishes. I have decided to share them in this article, in order to raise more people who will be interested in raising fish as pets. It is my hope that these fish facts will make you appreciate fish more.

Do you know that:

1. Starfish are not fish. Neither are jellyfish. 

2. Although the fangtooth fish is only a few inches long, it has teeth about the size of a human’s

3. The mudskipper is a fish that spends most of its time out of water and can “walk” on its fins. It carries a portable water supply in its gill chambers when it leaves the water. It can also breathe through the pores of its wet skin.

4. Catfish have over 27,000 taste buds. Humans have around 7,000.

5. Most brands of lipstick contain fish scales.

6. Lungfish can live out of water for several years. It secretes a mucus cocoon and burrows itself under the unbaked earth. It takes in air with its lung through a built-in breathing tube that leads to the surface. A lungfish has both gills and a lung.

7. Seahorses are the only fish that swim upright.

8. Some fish, such as the great white shark, can raise their body temperature. This helps them hunt for prey in cold water.

9. The oldest known age for a fish was an Australian lungfish. In 2003, it was still alive and well at 65 years old.

10. Fish use a variety of low-pitched sounds to convey messages to each other. They moan, grunt, croak, boom, hiss, whistle, creak, shriek, and wail. They rattle their bones and gnash their teeth. However, fish do not have vocal chords. They use other parts of their bodies to make noises, such as vibrating muscles against their swim bladder.

11. Fish can form schools containing millions of fish. They use their eyes and something called a lateral line to hold their places in the school. The lateral line is a row of pores running along the fish’s sides from head to tail. Special hairs in the pores sense changes in water pressure from the movements of other fish or predators.

12. Since a fish’s jaw is not attached to its skull, many fishes can shoot their mouths forward like a spring to catch startled prey.

13. Electric eels and electric rays have enough electricity to kill a horse.

14. Sharks are the only fish that have eyelids.

15. Fish have sleep-like periods where they have lowered response to stimuli, slowed physical activity, and reduced metabolism but they do not share the same changes in brain waves as humans do when they sleep.

16. Some fish, such as the herbivorous fish (grazers), often lack jaw teeth but have tooth-like grinding mills in their throats called pharyngeal teeth.

17. Most fish have taste buds all over their body.

18. An estimated one third of male fish in British waters are changing sex due to pollution in human sewage.

19. Saltwater fish need to drink more water than freshwater fish. Since seawater is saltier than the liquids in a fish’s body, water inside the fish is constantly flowing out. If they didn’t drink to replace the lost water, saltwater fish would dry up like prunes.

20. The oldest fishhook ever found dates back to about 42,000 years ago.

21. Most fish have little salt in them. Sharks, however, have meat as salty as the ocean they live in.

22. Most fish can see in color and use colors to camouflage themselves or defend themselves and their territory. Most fish have the best possible eyesight for their habitat and can most certainly see you peering at them in a fish tank. Some fish can see polarized and ultraviolet light.

23. The freshwater Pygmy and Luzon gobies of the Philippines, the saltwater Marshal Islands goby, and the tiny rice fish from Thailand all reach a maximum length of 1/2″, roughly the size of a grain of rice. They are typically considered the world’s smallest fishes.

24. The term “fish” is used when referring to one species of fish (e.g., 10 salmon are 10 fish). The term “fishes” is used when referring to more than one species (e.g., 10 salmon, 3 trout, and 1 angel fish are 14 fishes).

25. Most types of seahorses pair for life. Female seahorses lay their eggs inside a pouch on the male seahorse’s belly. When the babies are ready to hatch, the male holds onto a piece of seaweed with his tail and rocks back and forth until the babies pop out of his pouch.

26. A seahorse can move each of its eyes separately. One eye can look forward while the other looks backward. Like a Chameleon, Seahorses can also change their color to match their surroundings.

27. Unlike bony fish, sharks and rays do not have swim bladders. They have to swim all the time, even when they are sleeping. Otherwise, they will sink to the bottom of the ocean.

28. There are approximately 32,000 different kinds of fish in the world today, which is more than all the other kinds of vertebrates combined. Scientists are discovering new species all the time. Scientists have explored only 1% of the ocean depths. They believe millions of new kinds of animals and fish are down there, waiting to be discovered.

29. Sometimes tornadoes pick up fish while traveling over water and carry them over land, where the fish rain down. These “fish showers” have been happening for thousands of years. Roman writer Pliny the Younger describes this phenomenon in the 1st century A.D

30. Anableps, four-eyed fish, can see above and below water at the same time.

31. Male anglerfish are much smaller than the female. While the female can reach up to 24 inches long, the males barely reach 1.6 inches long and live as parasites on their mates. They stay together for life. As the male ages, he gets smaller and smaller. The female anglerfish’s light is always “on.”

32. The batfish plays dead when danger is near. It floats motionless on its side when scared, making it look like a dead leaf floating on the surface of the water.

33. A male emperor angelfish lives together with up to five female mates. If the emperor angelfish dies, one of the females turns into a male fish and becomes the leader of the group.

34. In Japan, the fugu, or puffer fish, is a succulent but lethal delicacy. It contains tetrodotoxin, a deadly poison. However, it is so delicious that Japanese gourmets risk their lives to prepare it. To make this high-risk dish, chefs must have a certificate from a special school that teaches preparation of this toxic fish.

35. Some fish do not have scales. Sharks, for example, have rough sandpapery skin instead of scales.

36. The slowest fish is a seahorse. It swims so slowly that a person can barely tell it is moving. The slowest is the Dwarf Seahorse, which takes about one hour to travel five feet. It even looks like it is simply standing up, not swimming.

37. The word “piranha” is from the Tupi (Brazil) pira nya and means “scissors.” Found in freshwater rivers in South America, piranhas have razor-sharp teeth. They typically eat fish, insects, seeds, fruit, and even larger animals such as horses. While there are no proven reports of piranhas killing a person, they do eat human carcasses.

38. The most poisonous fish in the world is the stone fish. Its sting can cause shock, paralysis, and even death if not treated within a few hours.

39. The biggest fish in the world is the giant whale shark, which can grow to nearly 60 feet, or the length of two school buses. It weighs over 25 tons and eats mainly plankton. It has over 4,000 teeth, though they are only 3 mm long.

40. A fish can drown in water. Like humans, fish need oxygen, so if there isn’t enough oxygen in the water, they will suffocate.

Amazing facts aren’t they? There’s more where that came from, and trust me; one of the best ways to appreciate fish is by studying them. To study them, you may need to raise them as pets through Aquariums. Watch them grow and appreciate their existence.
