Some are. But many will only cause injury with their hollow barbed fins, which can deliver a stinging protein. But some species, such as the striped eel catfish, can deliver a toxic mucus that may be fatal to humans. The edible portions of catfish do not contain any toxins.
A recent study suggests that about half of the 3000 known species of catfish are poisonous. Only a few species are poisonous enough to hurt humans (none in North America). The rest cause about the same amount of discomfort as bee stings. National Geographic also states that as the catfish grow, the venom glands shrink, indicating the venom glands are meant for defense while the fish is young.
The venom comes from glands near the pectoral fins. When the fins are grabbed the glands are ripped, releasing the venom.
The majority of catfish species have poisonous barbs located within their dorsal (top) and lateral (side) fins. If stuck with one of these, they can inject a toxin which causes a painful sting which usually resolves on its own after time. However, like any wound, it can get infected and it is advisable to clean and treat it. Only a select few of catfish species (located in areas of Southern Asia and India) have stings which could cause serious complications, or very rarely, death.
The catfish toxin is protein-based (like bee stings) and thus is treatable with meat tenderizer. Ammonia and vinegar will not be very effective, as they are alkali (base) treatments, to be used for acid-based toxins.
no part in the catfish is poisonous. I've checked inside.
The only really poisonous part of a catfish are the pectoral and dorsal fins.
They are only mildly venomous.
I don't think so.
They use their poisonous fins
It depends on the variety of catfish. Catfish vary in weight and size and some are poisonous. Some varieties of catfish will attack smaller fish, so selection for compatability is essential. ___________________________________________________________ Fish that will neither inflict harm on small catfish nor fit into the mouth of a bigger catfish. Catfish will consume anything that fits into their mouth and the majority of catfish have large mouths.
All catfish have a mild venom in their pectoral and dorsal fin spines. As for eating, thet are good if they don't come from polluted waters.
Catfish are dangerous fish like piranhas. They can be as big as small trucks and weigh up to 600 pounds! Their whiskers are poisonous and they sometimes produce electrical shock to attack other fish.
the catfish because of its poisonous barbs, the puffer fish because if the shark eat it, the shark's mouth will be pierce of the puffer fish spines, some jellyfish can kill it and maybe a stingray too.
bullheads, channel catfish, flathead catfish, and blue catfish.
I do not know of any catfish species that have poisonous whiskers. The whiskers are for feeling and tasting stuff on the bottom of the lake, pond or ocean. However, most catfish do have spines on dorsal (top) and side fins. It is possible to hold a catfish without getting stabbed by one of these sharp fins. If a catfish does happen to fin you and break skin, make sure you wash the wound thoroughly, especially if the catfish was a freshwater variety. If it is a saltwater catfish and you get finned by one, though it may hurt, wash your wound with ocean water. If the wound from a fin is deep, go to the ER and have them take a look to make sure the catfish did not injure any important parts of your body.
The biggest catfish is the Mekong catfish
well a blue catfish and a channel cat is to different species of catfish but there are both male and female blue catfish and Channel catfish
Catfish can swim. Some Amazonian catfish can eat people

a goonch catfish has teeth and a piraiba catfish doesn't but it has a surated mouth.
There are over 2000 species of catfish (order: Siluriformes), thus making them one of the largest fish orders. They vary greatly in body shape, pattern, and scale configuration. Catfish come from all types of environments in both fresh and salt water. Catfish belong to 34 families. Thirteen families are covered in this book. They include: the Aspredinidae (Banjo catfish), the Ariidae (Sea catfish), the Auchenipteridae (Driftwood catfish), the Callichthyidae (Armored catfish), the Chacidae (Squarehead catfish), the Doradidae (Thorny catfish), the Loricariidae (Suckermouth armored catfish), the Malapteruridae (Electric catfish), the Mochocidae (Naked catfish), the Pangassidae, the Pimelodidae (Flat-nosed catfish), the Schilbeidae (Glass catfish), and the Siluridae (Old-world catfish).
Not entirely.Most catfish species are freshwater. Though some catfish, like Hardhead catfish are saltwater catfish. Some catfish species can live in both fresh and salt water.
why do catfish not have scales?
A catfish is an omnivor
some species are but some like blue catfish, channel catfish, flathead catfish, and bullheads are edible and delicious.
Because the catfish has whiskers just like a pet cat does.
