Tetrahymena is a genus of free-living ciliates, examples of unicellular eukaryotes. The genus Tetrahymena is the most widely studied member of its phylum. It can produce, store and react with different types of hormones. Tetrahymena cells can recognize both related and hostile cells.
Leuciscus is a genus of fish belonging to the family Cyprinidae. They are inland water fishes commonly called Eurasian daces. The genus is widespread from Europe to Siberia. Species broadly distributed in Europe include the common dace Leuciscus leuciscus and the ide L. idus.
Pristichampsus is a non-diagnostic and potentially dubious extinct genus of crocodylian from France and possibly also Kazakhstan that is part of the monotypic Pristichampsidae family. As the type species, Pristichampsus rollinatii, was based on insufficient material when described in 1831 and 1853, the taxonomic status of the genus is in doubt, and other species have been referred to other genera, primarily Boverisuchus.
The Lessepsian migration is the migration of marine species along the Suez Canal, usually from the Red Sea to the Mediterranean Sea, and more rarely in the opposite direction. When the canal was completed in 1869, fish, crustaceans, mollusks, and other marine animals and plants were exposed to an artificial passage between the two naturally separate bodies of water, and cross-contamination was made possible between formerly isolated ecosystems. The phenomenon is still occurring today. It is named after Ferdinand de Lesseps, the French diplomat in charge of the canal's construction. The term was coined by Francis Dov Por in his 1978 book.
