You know normal links—they look [[like this]]. But did you know that you can use normal links to pages on any other wiki? This is called InterWiki linking, and applies to all wikis, not just Wikipedia's sister projects. You can link to a page on MeatballWiki by typing [[MeatBall:PageName]], for example. See Interwiki map.
However, links to Wikipedias in other languages are done a little differently. You can link to these by typing, for example, [[:de:Hauptseite]] (replace "de" with language prefix). The colon at the beginning prevents the link from becoming an interlanguage link, which shows up in the left sidebar.
To hide the prefix from the link, use the pipe trick.
Bonus tip: the same basic syntax works in the search box. (Try typing in Meatball:)
Pseudastacus is an extinct genus of decapod crustaceans that lived during the Jurassic period in Europe, and possibly the Cretaceous period in Lebanon. Reaching up to 6 cm (2.4 in) in total length, Pseudastacus had a crayfish-like build, with long antennae, a triangular rostrum and a frontmost pair of appendages enlarged into pincers, with those of females being more elongated. There is evidence of possible gregarious behavior in P. lemovices in the form of multiple individuals preserved alongside each other, possibly killed in a mass mortality event. With the oldest known record dating to the Sinemurian age of the Early Jurassic, and possible species surviving into the Cenomanian stage of the Late Cretaceous, Pseudastacus has a long temporal range and was a widespread taxon. Fossils of this animal were first found in the Solnhofen Limestone of Germany, but have also been recorded from France, England and Lebanon. All species in this genus lived in marine habitats.
