Hipposideros griffini

Griffin's leaf-nosed bat (Hipposideros griffini ) is a species of roundleaf bats. First seen in 2008, it was formally described in 2012. It is found only in Vietnam, and only at two places, Cát Bà Island in northern Vietnam, and Chư Mom Ray National Park. It is generally similar to the species complex of the great roundleaf bat (Hipposideros armiger ), with which it shares the habitat, but has distinguishing characters. It is relatively smaller and its sound navigation, echolocation, is different.

Animal name origin

Griffin's leaf-nosed bat is named after Donald Redfield Griffin, a professor of zoology at Rockefeller University in New York, who discovered animal echolocation.


Griffin's leaf-nosed bat is similar to the species complex of Hipposideros armiger, but with distinct acoustics, size, and DNA sequence. The sound frequencies for echolocation ranges from 76.6 to 79.2 kHz, which is higher than the frequencies produced by H. armiger subspecies, which range from 64.7 to 71.4 kHz. Its wing is 8.3–9 cm long. Its head measures 2.8–3. cm. Its nose is like a layer of leaves, and the anterior leaf has 4 supplementary leaflets of which the 2nd is the widest and longest, while the outermost is narrow and short. The tip of the ear, pinnais 2.35–2.65 cm wide and 2.75–3 cm high. The body colour varies from brown to gray.
