Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.
History is littered with hundreds of conflicts over the future of a community, group, location or business that were "resolved" when one of the parties stepped ahead and destroyed what was there. With the original point of contention destroyed, the debates would fall to the wayside. Archive Team believes that by duplicated condemned data, the conversation and debate can continue, as well as the richness and insight gained by keeping the materials. Our projects have ranged in size from a single volunteer downloading the data to a small-but-critical site, to over 100 volunteers stepping forward to acquire terabytes of user-created data to save for future generations.
The main site for Archive Team is at archiveteam.org and contains up to the date information on various projects, manifestos, plans and walkthroughs.
This collection contains the output of many Archive Team projects, both ongoing and completed. Thanks to the generous providing of disk space by the Internet Archive, multi-terabyte datasets can be made available, as well as in use by the Wayback Machine, providing a path back to lost websites and work.
Our collection has grown to the point of having sub-collections for the type of data we acquire. If you are seeking to browse the contents of these collections, the Wayback Machine is the best first stop. Otherwise, you are free to dig into the stacks to see what you may find.
The Archive Team Panic Downloads are full pulldowns of currently extant websites, meant to serve as emergency backups for needed sites that are in danger of closing, or which will be missed dearly if suddenly lost due to hard drive crashes or server failures.

How do we know a fish when we see one? Not as simple a question as you might think!
Fishes are animals that live and swim in the water (although you might see a fish like a mudskipper or walking catfish crawling on land), are cold-blooded (except for tunas and marlins and mako sharks that are warmer than the water), breathe using gills (usually, but lungfish and some others have lungs), have backbones (but not always of bone, such as in sharks, which are cartilage), have a scaly skin (except for eels, which are scale-less), and have various fins instead of limbs (except for a few that do actually have limbs, like lungfish and coelacanth). So, we usually know a fish when we see one, but there are lots of exceptions to our fishy definitions. Most people will recognize a "typical" fish like a goldfish, bass, bluegill, snapper, or grouper because of experience with aquariums, going fishing, or enjoying fish for dinner. And most people know that lampreys, sharks, rays, eels, seahorses, and other strange-looking aquatic creatures are fishes, while shellfish, cuttlefish, starfish, crayfish, and jellyfish (despite their names) are not fishes. But some fish species are weird enough, and look enough like salamanders or other animals, that it is not always easy to be sure that one is looking at a fish.
There are more than 32,000 described species of fishes, more than all the amphibians, reptiles, birds, and mammals combined. Fishes are an important food resource worldwide, and fishing pressure has caused many fish stocks to crash or be at risk. Both commercial fishermen and sport fishermen exploit coastal marine fish throughout the world, and fish farming is becoming more common, particularly for high-priced food fish such as salmon. Fishes are also popular as pets, with the aquarium trade in live fishes caught from the wild and being raised in captivity growing ever more popular. Fishes have had a strong role in human activities across many cultures, serving as deities, subjects of art and sculpture, legend and story, and more recently as the main characters in books and movies.
The main groups of extant fishes
Lampreys and hagfish (superclass Cyclostomata) are a group of jawless fishes at the base of the vertebrate tree of life, whose adults are characterized by a toothed, funnel-like sucking mouth and horny (not bony) teeth. Lampreys are best known for species like the marine lamprey, which bore into the flesh of other fish to rasp their flesh and suck their blood, although most species of lamprey are not parasitic. Hagfishes are also delightfully interesting creatures, capable of producing copious amounts of thick mucous, able to tie themselves in knots, and often found burrowed into the bodies of large fish that may still be alive. Biologists debate whether lampreys and hagfishes are closely related at the root of the vertebrates, or whether lampreys are more closely allied with other vertebrates than are hagfishes.
Cartilaginous fishes (class Chondrichthyes) are the chimeras, sharks, skates and rays. They have skeletons made of calcified cartilage rather than bone. Cartilage is tough and flexible, and can be just as hard and strong as bone, providing enough structural support to enable many sharks and rays to grow to very large sizes (the whale shark is the largest fish). This group includes the largest, fiercest, and most famous marine predators alive today. Most cartilaginous fishes live in marine habitats all their lives, but a few species of sharks and rays live in fresh water during all or part of their lives. All cartilaginous fishes are carnivorous and most species feed on live prey. There are some species that feed on the remains of dead animals and still others that are filter feeders. The class Chondrichthyes is further divided into subgroups, with Holocephali containing chimeras, and Elasmobranchii containing sharks (Selachii) as well as skates and rays (Batoidea).
Ray-finned fishes (Actinopterygii) are the most diverse of the major groups of fishes, containing more than 25,000 species such as gars, bowfin, eels, salmon, trout, catfish, piranhas, lanternfish, cods, anglerfish, tarpon, basses, cichlids, butterflyfish, wrasses, parrotfish, and many others. Ray-finned fishes share a set of basic characteristics, including a skeleton made up of true bone (although cartilage is also present in many places), an upper jaw that consists of two bones (the maxilla and premaxilla), and fins that are supported by a set of bony spines and rays covered with a thin layer of skin. The skull of ray-finned fishes is extremely diverse and highly adaptable. It contains a large number of different mechanisms for enhancing bite force and jaw protrusion, resulting in a wide range of feeding adaptations and ecological roles for the actinopterygian fishes.
Lobe-finned fishes (class Sarcopterygii) are a very special group of bony fishes with limb-like fins that are fleshy at the base and bones connected in series that look and function much like limb bones. The living sarcopterygians include lungfishes (which have both lungs and limb-like fins) and coealacanths, both of which are living representatives of diverse fossil groups. Lobe-finned fishes hold special interest to evolutionary biologists because members of this group gave rise to the first four-legged land vertebrates (tetrapods). In fact, all amphibians, reptiles, birds, and mammals are included as descendants in the tree of life of sarcopterygians—from that point of view, we are all just fancy terrestrial lobe-finned fishes!
Some of the major groups of ray-finned fishes (roughly in order of origin on the family tree) are:
Holostei: the gars and bowfins Osteoglossiformes: the bony-tongued fishes Elopomorpha: tarpon, bonefishes, eels, and gulpers Clupeomorpha: herrings, anchovies Ostariophysi: milkfishes, carp, danios, goldfishes, loaches, minnows, characins, piranhas, tetras, knifefishes, and catfishes Salmoniformes: salmon and trout Esociformes: pike and pickerel Osmeriformes: smelts and galaxiids Stomiiformes: bristlemouths and marine hatchetfishes Myctophiformes: lanternfishes Lampriformes: oarfish, opah, and ribbonfishes Polymixiiformes: beardfishes Percopsiformes: including cavefishes and trout-perches Batrachoidiformes: toadfishes Lophiiformes: anglerfishes Gadiformes: cods Ophidiiformes: pearlfishes Mugiliformes: the mullets Atheriniformes: silversides and rainbowfishes Beloniformes: flyingfishes Cetomimiformes: whalefishes Cyprinodontiformes: livebearers, killifishes Stephanoberyciformes: ridgeheads Beryciformes: fangtooths and pinecone fishes Zeiformes: dories Gobiesociformes: clingfishes Gasterosteiformes: sticklebacks Syngnathiformes: seahorses and pipefishes Synbranchiformes: swamp eels Tetraodontiformes: triggerfishes, filefishes and pufferfishes Pleuronectiformes: flounders and flatfishes Scorpaeniformes: scorpionfishes and sculpins Perciformes: 40% of all fishes including anabantids, basses and sunfish, cichlids, gobies, gouramis, mackerel, tuna, perches, scats, whiting, wrasses
