Hello and happy New Year to all of our loyal fans! Since we’re entering a new year, we figured there’s no better way to start off than by showing you 50 new and interesting fish facts for 2015. Take a spin through our list and learn some strange, funny, and interesting things you never knew about our scaly little friends.
1. Despite being fish and not mammals, many shark breeds give birth to live young.
2. Under the right conditions (usually resulting from poor care), a Goldfish can lose its color.
3. During the disco era, a rather inhumane fad existed in which people would wear shoes with goldfish placed in compartments beneath their feet.
4. A Goldfish that is living under optimum conditions can live to be over 30 years old.
5. One more Goldfish fact for you: Did you know that the Goldfish can trace its origins back to China, where its ancestor the Carp first lived?
6. While the human heart has four chambers and the hearts of reptiles have 3, fish hearts only feature two chambers.
7. The most plentiful and populous fish in the world is the Brittlemouth. Chances are, you’ve never seen one as they’re quite small, blend in well with sand, and live in very deep waters.
8. Fish don’t taste solely through their mouths. Most fish have taste buds all over their bodies, including on their tales, fins, and scales.
9. Mainly due to pollution, over 30% of the male fish living in British waters are in the process of changing gender.
10. Crazy as it sounds, it’s possible for a fish to drown in water. Fish need oxygen to breathe and if they’re stuck in an area where the oxygenation is insufficient, they can die as a result.
11. The Whale Shark may be the biggest fish in the world, but it certainly doesn’t have the biggest teeth. Of the thousands of teeth in their mouth, very few ever grow to a length of more than 3 millimeters. This means that your teeth dwarf those of the ocean’s largest fish.
12. The two most primitive fish that are still extant today are the Hagfish and the Lamprey.
13. The Batfish has learned to play dead when predators are near, taking on the appearance of a dead floating leaf1.

16. Even though freshwater makes up less than 1% of the water on Earth, 40% of aquatic species call it home.
17. Not all fish are entirely mute. Some can create noise by grinding their teeth.
18. It is very important to do your research before buying tropical fish for a home aquarium. Over 95% of their deaths are caused by poor nutrition and improper housing2.
19. A school of fish is directed by the fish swimming in the very middle, not by the fish in the front of the pack.
20. Tuna can swim much more quickly than humans can run. Some tuna are able to exceed speeds of over 40 mph.

23. Here’s a pretty basic one, but in case you didn’t know, fish are vertebrates.

34. Due to the amazing amount of energy expended during spawning, nearly all Salmon will die within two weeks after the cycle is complete.

38. Together with the Lamprey, the Hagfish are the only jawless fish still alive today.
