Land predators (Fissipedia) is the designation for a biological in the modern system is no longer used subordination of predators , in their terrestrial representatives were summarized. The "land carnivores" stood in opposition to the other, correspondingly known as "water carnivores " (Pinnipedia), subordination with aquatic carnivores, which continues to exist in the current system as the seal taxon .
According to the current state of science , the main lines of modern carnivores emerged from the original predators, the feline (Feliformia) and the canine (Caniformia). The seals, however, do not form a separate line of development, but a natural family group ( Monophylum ) within the canine species. The “land carnivores” are therefore not a natural family group, but rather paraphyletic because by definition they do not include the seals as descendants of the youngest common ancestor of feline and terrestrial canine.
Naming
The name "Fissipeda" was introduced into literature by Blumenbach in 1791 , but mostly used as "Fissipedia". Both name variants are derived from the Latin findere 'split' and pes , pedis 'foot' and mean " split- foot". This designation refers to the difference of those pinnipeds or "pinnipeds" because the toes of the paw of Spaltfüßer are "free" and not like each other through with the pinnipeds webbed to a fin connected.
