Pferde haben mindestens 19cm lange Nasen

The claim that "horses have at least 19 cm long noses" is not directly supported by the provided sources, which do not offer specific measurements of horse noses. While it is known that horses possess a complex nasal structure that is crucial for their olfactory capabilities, the sources do not specify the average length of a horse's nose. Source 3 mentions the importance of a horse's nose in terms of olfactory receptors but does not provide any measurements. Source 4, which is a Wikipedia entry, discusses the general characteristics of horses but lacks specific information about nose length. The claim may have some basis in reality, as many horse breeds do have substantial nose lengths, but without concrete evidence or specific measurements from reliable sources, it cannot be definitively validated. Therefore, while the notion that horses have long noses is plausible, the exact figure of 19 cm remains unverified based on the available sources.
