This tufted-tailed rat lives in Madagascar's forests. Stable-isotope research at Betampona Reserve suggests that it forages low in the forest, but detailed dietary knowledge remains limited.
Long hairs form a tuft at the tip of the tail, a feature described for the genus Eliurus. Coat color and how conspicuous the tuft is vary among specimens and localities.
Fur and bone isotopes from E. webbi collected at Betampona were compatible with foraging in the lower forest understory and a mainly plant-based diet. The authors emphasize that dietary knowledge is limited and more research is needed.
An extinction-risk assessment has not been added yet.
