Interesting Animal Facts: Fish
In the deepest parts of the ocean and other bodies of water, a great deal of fascinating activities, habits, and traits emerge. From the Rainbow Trout to the Yellowtail Flounder, there are more than 28,000 different types of fish living in our global waters. In this article, you will learn how some fish species cope with their environment, as well as other fun facts concerning different kinds of fish, including the piranha, goldfish, and salmon.
Deep in the ocean, many fish are known to engage in hermaphroditism, where some species actually change sex in response to hormonal cycles or changes in their environment. There are other kinds of fish that are simply equipped with both female and male sex organs.
With teeth sharp enough to bite through a steel fishing hook, the piranha is a carnivorous freshwater fish that dwells in the rivers of South America. If you’re worried whether or not you can meet up with this toothy fish, piranhas typically live in Amazonian, Guianas and Paraguayan river systems. Yet in still, some are occasionally found in warmer waters of North America (most likely a former resident of an aquarium), but usually do not survive very long. Despite their reputation and appetite for meat and flesh, piranhas are not as much as a threat as humans would like to think. Locals who live close to piranhas swim in waters filled with the fish without any attacks or even a scratch on the skin.
