Animalia Paradoxa facts for kids

Animalia Paradoxa is the label given to a few species of animal, listed in Carolus Linnaeus early editions of Systema Naturae. Linné thought that these animals did not make sense. Today, such animals are usually called Cryptids. The respective section lists fantastic creatures found in medieval bestiaries as well as those reported by explorers from abroad and gives explanations to why they are excluded from Systema Naturae. According to Swedish historian Gunnar Broberg, it was to offer a natural explanation and demystify the world of superstition. Paradoxa was dropped from Linnaeus' classification system as of the 6th edition (1748).

Cryptic creatures

Included in the 1st (1735) edition:

Hydra: in 1735 Linnaeus inspected the alleged remains of a Hydra in Hamburg which turned out to be made from weasels and snake skins.
Rana-Piscis: a South American frog which is significantly smaller than its tadpole stage; it was thus (incorrectly) reported to Linnaeus that the metamorphosis in this species went from 'frog to fish'. In the 10th edition of Systema Naturae, Linnaeus named the species Rana paradoxa, though its genus name was changed in 1830 to Pseudis.
Monoceros is in reality Monodon.
Pelecanus: "Linnaeus thought [pelicans] might reflect the over-fervent imaginations of New World explorers"
Satyrus: Linnaeus wrote "with a tail, hairy, bearded, with a manlike body, gesticulating much, very fallacious, is a species of monkey, if ever one has been seen."
Borometz (aka Scythian Lamb) "Linnaeus [...] had seen a faked vegetable lamb taken from China to Sweden by a traveler"
Phoenix
Bernicla (aka Scottish Goose) Frederick Edward Hulme noted: "[The] barnacle-goose tree was a great article of faith with our ancestors in the Middle Ages."
Draco: Linnaeus wrote that it has a "snakelike body, two feet, two wings, like a bat, which is a Lacerta alata or a ray artificially shaped as a monster and dried."
Automa Mortis Linnaeus wrote "The DEATH-WATCH produces the sound of a smaller clock in walls, is named Pediculus pulsatorius, which perforates wood and lives in it".

Four taxa were added in the 2nd (1740) edition:
