Can you imagine a catfish bigger than a boy? There are more than 1，000 kinds of catfish；28 species are found in the United States' lakes and rivers． This huge family has some mighty strange members. Let's meet a few.
Walking catfish．Nature's feisty little catfish，found in southern Florida，has an extra lung for breathing on dry land. When its swimming hole dries up，the walking catfish waddles on stiff forward fins in search of another lake or stream．If an enemy attacks，the fish flares（展开）its top and front fins and leaps at the attacker to scare it off．
Armored catfish．This catfish has heavy，bony plates protecting its body. The shell makes the fish difficult to bone. To cook it，throw the fish whole into a fire. When it is done，break it open for eating．Some armored catfish are found in Florida，but the 100-pounders live in South America．
Rounding out the family of strange catfish are talking catfish，which make growing sound when you pull them from the water；climbing catfish，which move quickly up shore brush in search of food；electric catfish，which can deliver a mild shock；and blind catfish，which settle in the inky blackness of underwater caves．Blind catfish find food through taste buds in their eight whiskers（须）．
Most catfish have four whiskers on the upper jaw and four on the lower jaw. Sensory holes on these whiskers help the fish smell and taste food even in the muddiest of water．The United States does not have catfish anywhere near the size of those in South America．But in some large U.S，rivers，blue and flathead catties do top 100 pounds．
Most of the catfish you are likely to catch will be much smaller，about frying pan size．When you catch one，remember that the top fins and the forward fins have poison glands（腺）at their bases. They can give you painful wounds （…）
