The Mount Lyell shrew (Sorex lyelli) is a species of mammal in the family Soricidae. It is named for Mount Lyell in Yosemite National Park, the area where the shrew has been most commonly found.

Range

It is endemic to a small area of the Sierra Nevada in California, United States.[1] The range is located in Fresno, Mariposa, Mono, and Tuolumne counties between an elevation of 2,100–3,630 metres (6,890–11,910 ft). It is typically found in sub-alpine riparian areas near fast-running streams.[3]

Description

The shrew is between 8.9 and 10 centimetres (3.5 and 3.9 in) long[4] and weighs 4–5 grams (0.14–0.18 oz).[5] It has 32 teeth.[4]

Observations

In November 2024 it was photographed alive for the first time, 100 years after its discovery, by a team of student researchers from the California Academy of Sciences.[6][7] The team, consisting of Vishal Subramanyan, Prakrit Jain, and Harper Forbes, captured images of the elusive mammal in the Eastern Sierra Nevada.[8][9][10][11]

In November 2024, researchers from UC Berkeley and the University of Arizona captured the first live photographs of the Mount Lyell shrew in its natural habitat, providing new insights into its ecology and distribution.[1]
