スミソニアン国立動物園さんのインスタグラム写真 - (スミソニアン国立動物園Instagram)「The African crested rat is hardly the continent’s most fearsome-looking creature—the rabbit-sized rodent resembles a gray puffball crossed with a skunk—yet its fur is packed with a poison so lethal it can fell an elephant, and just a few milligrams can kill a human. In a Journal of Mammology paper published yesterday, researchers from the Smithsonian Conservation Biology Institute, University of Utah and National Museums of Kenya found the African crested rat is the only mammal known to sequester plant toxins for chemical defense, and they uncovered an unexpected social life—the rats appear to be monogamous and may even form small family units with their offspring.
