Is a crayfish the same thing as a crawfish?

Yep.  Same thing as a crawdad too.  \n\nBut there's no such thing as a craydad.  Go figure.

well, it definitely sounds like an arthropod, so the place to look would be a book or website with lots of pictures of different kinds of Arthropods - crustaceans, spiders, centipedes, insects, and more, they're all in the phylum Arthropoda.  Your arthropod sounds like it's in one of the lesser known groups.

You're right, it's not the best analogy.  Apples and oranges are both fruits, they both grow on trees, they both have seeds in the middle; however, they have differences: you can eat the skin of an apple and not an orange, an orange has segments, but an apple doesn't.  I guess it's all in the way you look at it!

They are pretty much the same.   A stoat is also known as a Short-Tailed Weasel.  All weasels are in the same family (Mustelidae).

What about them?\n\nThere are literally millions of different species of invertebrate, ranging from barely mobile blobs of slime like the Placoderms to mysterious and predatory deep-sea giant squid to parasitic wasps that lay their eggs in caterpillars to caterpillars that eat leaves and get parasitized.\n\nThere is no way to generalize about their behaviour as an entire group.  A giant Australian freshwater lobster has a completely different life than a leaf-cutter ant living high in the forest canopy of the Amazon rain forest or an individual coral polyp forming part of a reef in the Caribbean.

Many people want to know what the difference is between alligators and crocodiles. There are many differences, most of which are not easy to see. One of the differences that you can see is the shape of the head. Alligators have a broader, more rounded snout while crocodiles have a narrower, more pointed snout. If you look at the side of a crocodile's mouth, you'll notice the fourth tooth on the bottom jaw sticks outside of the top jaw and into a groove. The upper and lower teeth of a crocodile stick outside the jaws while the bottom teeth of the alligator fit into sockets in the upper jaw.\n\nAlligators outnumber crocodiles 1,000 to 1 in the wild in North America. The American crocodile is considered endangered, with a wild population of less than 500. The American alligator population is estimated at about 1.5 million.

Yes, or at least from some predatory archosaurs. There are currently two strong theories, each with their supporters: birds are dinosaurs (Padian, Chiappe, etc.), or birds are non-dinosaur archosaurs (Feduccia).\n\nIf they evolved within the Dinosauria, as much evidence seems to show (see link), then according to a cladistic classification they ARE dinosaurs (the same way that we are Sarcopterygians, even if we're not fish-like anymore).

Dinosaurs were members of the SuperOrder Dinosauria. No member of Dinosauria are alive anymore.\n\nReptiles, like Komodo dragons or crocodilians are not and never were dinos- a seperate branch of the evolutionary tree.\n\nThere are kinds of fish (coelocanth, shark, etc.), plants (ferns, fungi), reptiles (crocs), insects, and other groups that are very similar to their prehistoric counterparts- but none of these were dinos either.

crocodiles are a type of reptile. they might be descendants of dinosaurs but are not classified as a type of dinosaur

"Crabs" is a name for pubic lice. Call it what you want but they are little tiny bugs that live in your pubic hair and live off your blood by bitting your flesh. They are the same thing as head lice so if you get head lice you should also get checked for pubic lice.

Lobsters are arthropods.  They are related to spiders, insects, millipeded, centipeded, crabs, shrimp, etc.  They have what is called an open circulatory system.  It differs from ours in that they have open areas that collect the blood before it is moved to other parts of the body.  Their heart is on the dorsal part of the body.  It runs along the middle back of the animal.  It resembles a muscular tube.  Ours is located on the ventral side protected by the sternum and ribs.

Interesting question, because it shows the difference between two levels or types of speech.\n"Bug" is a common term that people use with different meanings.\nIn contrast, scientific names of natural groups have the same definition and content all around the world. In that sense, 'Insecta' (insects) is a class of arthropods that includes animals with articulated exoskeleton, 3 pairs of legs, 1 pair of antennae, and body divided into head, thorax and abdomen (among other characteristics). The definition of insect is the same everywhere.\nSo, those terms are not opposites, but whether one comprises the other will depend on the popular definition of 'bug'. Some people include also spiders, which are not insects, in the 'bug' category. For others, bugs are only beetles, and therefore would be included in the definition of Insects.\nI looked in my dictionary and it said:\n1. A true bug. \n2. An insect or similar organism, such as a centipede or an earwig. \n3. A disease-producing microorganism.\n\nSo I'd say that for most people, bugs are "insects + others" as you put it.

It would be really nice if people didn't just take guesses at the answers. Every single person who has answered so far has given false information.\n\nCrocodiles are not marine animals. Some species of crocodiles will live in brackish or tidal water and travel in the ocean. Many crocodile species are entirely confined to freshwater habitats. Some alligators will also live in brackish or tidal water and travel in the ocean.\n\nCrocodiles are notlarger than alligators. Many crocodile species are much smaller than the majority of alligator species.\n\nNor do crocodiles have broader snouts, in fact exactly the opposite. With the exception of one species alligators  will always have a much broader snout than a crocodile of the same size. Alligators have a wide "U"-shaped, rounded snout (like a shovel), whereas crocodiles tend to have longer and more pointed "V"-shaped noses.\n\nThe other easy to spot difference is that in alligators the top jaw is wider than the bottom, whereas in crocs the two jaws are the same width.

Snails are mollusks; that puts them in the same phylum as clams, oysters and cuttlefish.

A jig is used to weigh down what ever it is your fishing with. You can put just about anything on a jig. If the jig has a skirt, you don't have to use a trailer, but I think it will work better with one. Try Booyah jigs. They have great colors, and I would suggest a 3/8 ounce size. Then get Yum crawfish chunks. Cast it out, let it sink, and then slowely tug on it so it looks like a crawfish swimming across the bottom. You can get different jig heads that do different things. Some glide through the water better, some cut through weeds better, etc.... Good luck.
