Piranha is also the name of RedHat's redudant server package. It uses the Linux Virtual Server software found at http://www.linuxvirtualserver.org and gives it a friendly PHP configuration interface accessible through HTTP. Piranha is free to download, though also available in RedHat's High Availability Server package for around two thousand dollars.

Piranha was the name of a terrible hack of Pac-man. It was released in 1981 by "GL" as it is quoted on the attact mode screen. You played a piranha trying to eat all of the dots in a free-form area (no walls to speak of), with the ghosts replaced by Octopi or some sort of squid monster. The graphics and sound are terrible, and the play control is awful. The ghost logic seems to still be used to having walls, so they make some poor decisions when trying to hunt you down. All in all, not a very good hack.

An insane rarity (if it even still exists) in arcades, this hack is playable in MAME with the standard pacman driver.

Piranhas are medium-sized, carnivorous tropical fish native to South America. There is some considerable confusion over the definition of the piranhas. The common name has been hopelessly applied to any and all voracious carnivorous fish, whether or not it is biologically a member of the piranha subfamily, the Serrasalminae. Even further complicating the definition of piranhas is the aquarium trade, which often applies upwards of five or six common names for a single species, and often uses the same common name for up to ten different species. The result is a horrible mess of confusion, frustration and tears. What follows is a discussion of the piranhas as best defined by modern biological classification.

General Biology

The name Piranha, or more appropriately Piraña, is etymologically from the Tupi-Guarani, and means toothed-fish (pira=fish, ranha=tooth). They are also often called Caribe, named after the Carib natives who were known to the Spanish explorers (conquerors) to be both fierce and cannibalistic.

They are deep-bodied laterally-compressed (imagine a dinner plate) fish with very prominent jaws. They are best known for their highly developed and very sharp teeth, which can grow to be 3/4 cm long. Their teeth are so sharp that people who have been bitten claim not to have felt the contact at all, and in fact until they saw the blood had no idea they were hurt. Piranhas have well developed lateral lines, and a prodigious sense of smell. Their vision, on the other hand, is quite poor. They are thus well adapted to living in the murky waters of South American rivers.

Neonate piranhas feed on invertebrate prey (zooplankton, insects) but as they grow they quickly shift to higher animals like fish, birds and rodents. They school, and attack in packs. When piranhas attack a larger prey, they go into a frenzy, causing the water around them to roil and turn red with blood. In this feeding frenzy, they often bite one another, and are known to be voraciously cannibalistic.

The above description of their feeding behaviour is generally valid for the genera Pygocentris and Serrasalmus. It falls to pieces, however, with the other members of the subfamily, the genera Pristobrycon and Pygopristis, which are totally herbivorous. They feed on fruit and seeds that fall from trees into the water, and can be kept in captivity on commercial bird seed1.

The piranha is a preferred prey of many birds and larger predators in South America. In particular, it is targeted by the caiman and crocodile during the end of the rainy season (as the rivers and tributaries dry up, the piranhas are easy prey).

Conservation status

Unlike many other species native to South America, the piranha is not threatened by humans. In fact, the piranha presents the opposite problem for the conservation biologist: they are quite hardy animals and have been transported all over the globe due to the aquaculture hobby. These animals are released into the wild relatively infrequently, but have managed to survive in both North American and European waterways. Luckily enough, they are normally killed by the cold winter; they do not survive if the water temperature drops below 230C. However, there is considerable concern about a possible introduction leading to a permanent population in the southern United States (California, Texas and Florida), resulting in the banning of the species from some southern states.

Relationship to humans

The piranha, despite horrible movies to the contrary, has never been a confirmed predator of human beings. However, humans are often injured by piranhas, especially when fishing either for the species or for another fish in the same waterway. In many areas in South American, the piranha is fished locally for food. They apparently taste remarkably like the crappie, and are remarkably easy to catch (a line, a hook and any animal protein will do).

Taxonomy

There is a great deal of confusion as to what constitutes the piranha family, subfamily or genus. What is presented below is the best classification currently available based on both classic morphlogical and modern genetic techniques.

Order: Characiformes 2
Family: Characidae
Subfamily: Serrasalminae

Genus Pygocentrus (the true piranhas)
P. piraya -- Red piranha
P. cariba -- Black-spot piranha
P. nattereri -- True piranha


Genus Pristobrycon
P. aureus
P. baratai
P. striolatus -- Striolated piranha
P. maculpinnus
P. careospinus
P. calmoni


Genus Serrasalmus
S. spilopleura -- Gold piranha
S. rhombeus -- Red-eyed piranha
S. maculatus
S. altispinnis
S. altuvei
S. brandti
S. compressus
S. eigenmanni
S. elongatus -- Slender piranha
S. irritans
S. gibbus
S. gouldingi
S. hastatus
S. hollandi
S. humeralis
S. manueli
S. marginatus
S. medinai
S. nalseni
S. neveriensis
S. nigricans
S. sanchezi
S. serrulatus


Genus Pygopristis
P. calmoni
P. denticulata -- Lobetoothed piranha
P. striolatus


1 Wonderful little facts, such as these, help to contribute to the aforementioned weeping and frustration.
2 Formerly part of the Cypriniformes, the same family as the goldfish, carp etc.

Piranha: Cheap 1978 horror flick

1978 was a good year for horror films. Dawn Of The Dead, Halloween and The Amityville Horror all terrified entire audiences at a time. Jaws 2 was threatening to be nearly as good as the original, and The Swarm was bravely unsuccessful attempt to continue the mutated-animals-gone-mad theme. In amongst all this was Piranha.

Later, its director, Joe Dante would move on to The Howling, Gremlins, Innerspace and Small Soldiers. For now, then, it would be charitable to put Piranha down to inexperience. Piranha must, one feels, be the woeful evidence of a sharp learning curve. It's entertaining, in a way, but mainly because of its inedequacies.

A distinct lack of originality marrs the film from the very beginning. Clearly taking a leaf from Jaws' script, a couple of teenagers ignore all common sense and gleefully strip off before plunging into the dark and ominous stretches of a mysterious, fenced-off pool. An entire troop of cellists immediately begin to play an appropriately dirgeful score, whilst the young chap bitches bitterly about being a bit bitten. However, ignoring both the unusual nibbling and the sudden orchestral interest, the two bravely plunge on for the centre of the pool whereupon they are unceremoniously devoured. None of the cellists help, incidentally, choosing instead to perform a rousing chorus of appropriately spooky music.

This dodgy beginning quickly leads on to a dodgy middle and, eventually, a rather dodgy end which carefully leaves the way open for James Cameron's tacky sequel - yes, he's another director who has benefited from the sharp learning curve of early mutant animal horror. Within the dodgy middle portion we discover the usual stuff - secret government experiment, accidental release into large river, that kind of thing. Oh, and the large river just happens to be full of kids. And people on boats. Stupid people on boats, come to think of it, who can't seem to withdraw a limb from the water once they've realised that something's not quite right. It's the foaming and the bright red 'blood' that tips them off, albeit a little slowly.

There is only one conclusion. It's parody. It has to be. Writer John Sayles, sitting down to his first screenplay ever, must have decided to take a piranha-sized bite at Jaws and produce the perfect parody. But if it is parody, then deadpan simply doesn't describe it. There is no hint of intentional humour, no tiny glimpse of sarcasm at work. The whole film, from beginning to end is a non-stop rollercoaster of really bad horror, littered with cliche and stock characters, however entertaining it turns out to be. And it is entertaining, in its own way. Desperate for 94 minutes of fun? Then rent it, but don't buy...

Piranha was originally released in 1978, starring Bradford Dillman, Heather Menzies and Kevin McCarthy. The most notable of these is McCarthy, who starred in the original Invasion Of The Body Snatchers. Originally, Eric Braeden was cast in Dillman's part, and though he pulled out to pursue an alternate project, some of the swimming footage still shows Braeden. Which is fascinating, really. Oh, all right - it's pointless trivia. But hey - it gives you something to do when you're bored in the middle of the film: spot the Braeden!
