Species

There are currently four recognized species in this genus:[1]

Distribution

The genus has been reported from the upper Orinoco, the eastern, north-flowing Amazon tributaries, and the Tocantins River.[2]

Description

Leporacanthicus species have large teeth in the upper jaw; usually there are only two teeth on each premaxilla, the inner teeth very long. Species of Leporacanthicus are medium-sized loricariids with a narrow, pointed head, round lower lip, and fleshy tentacles on the upper lip. The colour pattern is generally dark gray to black with white to golden spots or a light gray with medium-sized black spots. The abdomen is naked (scaleless and unplated). The caudal fin is straight and angled posteroventrally.[2] L. galaxias are basic black with many white spots.[3] L. triactis are brown, gray, or charcoal black, save for vivid orange or yellow blotches on the spines of the non-paired fins.[4]

It has been hypothesized that the enlarged teeth of the upper jaw are used to remove snails from their shells. This has been observed in L. joselimai, but specimens from Venezuela seem to have a lot of caddis flies as well as freshwater sponges in the gut.[2]

In the aquarium

Leporacanthicus are called vampire plecostomus in the aquarium literature in reference to their large teeth that are characteristic of the genus.[2][3][4] These species should be fed invertebrate matter such as mollusks or crustaceans; however, they will accept other foods as well. These fish are territorial species.[3][4] L. galaxias originates from oxygen-rich environments and should be provided with such a habitat in the aquarium.[3] This fish is not often seen during the day.[3] Breeding has been accomplished for L. galaxias but not documented.[3]

gollark: Thus, python-able image file.
gollark: A fun feature of python is that it actually will run `__main__.py` or something from ZIP files, and ZIP files are weird and backward and can be concatenated onto the end of another file without decoders caring much.
gollark: PNG has some mandatory header parts at the start and I don't think you could make something both a valid PNG and valid in any modern executable format.
gollark: PNG files aren't "run", they're opened and displayed by some sort of image viewer program. And no PNG has no metadata, or it's not actually a valid file. While you can mix hidden data in with the image data, computers will not randomly run that, barring some sort of extremely bad vulnerability.
gollark: It's probably going to be treated as multiple sub-objects for collision detection though.
