Small enough to climb onto the inflorescence, or flower cluster, of a palm plant, this tiny mouse opossum belongs to a newly re-classified South American species: Zeledon’s mouse opossum (Marmosa zeledoni). Minute marsupials like this one are rarely seen at flowers, but this species may be a pollinator for some neotropical palms.
Zeledon’s mouse opossum was previously lumped together with the Mexican mouse opossum, Marmosa mexicana. But in a recent study partly funded by the National Science Foundation, Curator Rob Voss of the Division of Vertebrate Zoology at the American Museum of Natural History and colleagues examined roughly 1,500 mouse opossum specimens, some collected from as far back as the 1800s. They determined that what had been known as the Mexican mouse opossum could actually be subdivided into two different species.
