Is The Bluegill Fish Dangerous?
Bluegills are one of the most common types of gamefish. This freshwater fish is found in water all over North America, from Mexico all the way up to Canada. You’re likely to find bluegills living in a pond, lake, or stream near you. But recently, posts have been going around on Facebook, stating that bluegills are related to piranhas and just as deadly.
So, what’s the truth behind the story? Well, you’ll be glad to hear that there’s no evidence whatsoever that bluegills have ever caused a human death. Bluegills are a type of sunfish and are also referred to as blue sunfish, copperbellies, copperheads, and bream.
There’s no relation or link at all between the bluegill and the piranha. The only thing these two species have in common is that they’re both freshwater fish, but with very different habitats. The piranha’s natural habitat is in the rivers and basins of South America. Bluegills can be found all over Northern America – but there’s no overlap at all with piranhas.
Bluegill are quite a small fish, growing up to about 12 inches in total. Rather than being a predator, bluegills are prey to everything from trout and muskies to herons, turtles, and otters. And to reassure you, a bluegill’s spikes on the dorsal fins are not poisonous, either! While some fish may have toxins in their spikes, this isn’t true for bluegill.
Bluegills are one of the most common types of fish for fly fishers and anglers to target. There’s no reason at all to think that bluegill fish are a hazard. If you give it a try, you’ll discover that fishing for bluegill is great fun! These spirited little fish can put up a mean fight when you hook one. (They taste good, too!)

What Do Bluegills Bite?
Now we know that bluegills do not eat or kill humans, and they are not known to bite the human body. In fact, the bluegills’ teeth are very small. Even if bluegills did try to bite humans, they would struggle to break the surface of the skin. So people have nothing to fear from the harmless bluegill. That just goes to show how little bluegills have in common with piranha. They are very different (and less threatening!).
So what do they actually eat? Bluegills mainly live off a diet of worms, crustaceans, smaller fish, and insect larvae. The bluegill is partial to caddisflies, dragonflies, and mayflies, and will pick them off the top of the surface. They will also eat them in larvae form, lower down in the river, or along the bottom. Bluegills are omnivores, so underwater vegetation is also a source of food for the bluegill species, too.
What Eats Bluegill?
The truth is that we’re much more likely to kill and eat bluegill than the other way around! Many people enjoy fishing for this species, as they are boisterous and put up a lively fight, making it into a great game. The bluegill fish is a tasty food too, especially when caught fresh and panfried. Kids often start learning how to fish by catching this abundant little sunfish, before moving on to game fish like trout or bass.
Bluegill aren’t just threatened by people, however. As they are so defenseless, many different species of fish, birds, and animals like to snack on bluegill. Larger gamefish will happily kill and eat bluegill. But they are also prey to birds, including herons and kingfishers. Even land animals like raccoons and otters count bluegill as a good source of food.

Are Piranhas Dangerous?
The quick answer is that yes, piranhas are dangerous. They have sharp, powerful teeth that can give a nasty bite. But there’s a little bit more to it than that, because piranhas are actually pretty lazy! More often than not, piranhas will scavenge meat from dead creatures in the water than attack an animal or human. 
If you ended up in the water with piranhas, they would be more likely to see you as a danger than as a source of food for them. That’s because piranhas aren’t designed to eat people – we’re not their natural prey. However, if they feel threatened, they may attack as a form of self-defense, so piranhas are still a real hazard to humans.
