Answer 2

Catfish (order Siluriformes) are a very diverse group of bony fish. Named for their prominent barbels, which give the image of cat-like whiskers, catfish range in size and behavior from the heaviest, the Mekong giant catfish in Southeast Asia and the longest, the wels catfish of Eurasia, to detritivores (species that eat dead material on the bottom), and even to a tiny parasitic species commonly called the candiru, Vandellia cirrhosa. There are armour-plated types and also naked types, neither having scales. Despite their common name, not all catfish have prominent barbels; what defines a fish as being in the order Siluriformes are in fact certain features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food, and some are exploited for sport fishing, including a kind known as noodling. Many of the smaller species, particularly the genus Corydoras, are important in the aquarium hobby.

The name dogfish is applied to a number of small sharks found in the northeast Atlantic, Pacific, and Mediterranean, especially to those in the three families Scyliorhinidae, Dalatiidae and Squalidae. Although often used in reference to Scyliorhinus canicula, the name is applied only loosely and does not usually signify a close taxonomic relationship.

(Squalus acanthias) -- This small, slender shark has a flattened head and a snout that tapers to a blunt tip. It averages 2 1/2 to 3 feet in length with the largest growing to 4 feet or more. Records show that they can live from 25 to 30 years.

Its mouth is full of low, flat, grinding teeth like the smooth dogfish, but the spiny dogfish also possesses an extra set of small, very sharp teeth.

The spiny dogfish, Squalus acanthias, is the most common shark in the western Atlantic. It hunts both alone and in groups with other dogfish. It eats small fish, squid, and crustaceans, and has extremely strong jaws for crushing shells.

Dogfish are considered a nuisance by fishermen because they will latch on to almost anything put in the water, including human hands. Fishermen kill them when caught which, along with pollution, has contributed to a sharp decline in population in Puget Sound. It is now illegal to kill or mutilate them when caught even though at a time, they were considered a delicacy by Europeans.

Care must be taken when handling dogfish due to the two venomous spines at the back of both dorsal fins. The venom is not likely to cause major damage, but the wound can take months to heal.

Answer 10

There's also the Opelousas, and the Yellow Cat, which are darn good fried or added to gumbo. Personally, I prefer the channel cat because they swim a lot against currents. The flavor is amazing.
