Suncus cf. etruscus

Pigmy Shrew (Suncus etrucus)

This is indeed ‘pigmy’ news in the history of a limestone quarry site at Aruvakkalu. Our fellow biodiversity expert, Sampath De A. Goonatilake while at the limestone quarry site earlier this year ‘stumbled’ upon this tiny shrew, no bigger than that of a watch strap in size.

The Etruscan shrew (Suncus etruscus), also known as the Etruscan pygmy shrew or the white-toothed pygmy shrew is the smallest known mammal by mass, weighing only about 1.8 grams on average.

This pigmy shrew grows up to about 4 cm in body length excluding the tail. It is characterized by very rapid movements and a fast metabolism, eating about 1.5–2 times its own body weight per day. It feeds on various small vertebrates and invertebrates, mostly insects, and can hunt individuals of the same size as itself. It has widely distributed from Europe to Malaysia including North Africa. In Sri Lanka it has identified as a Data Deficient Species (DD) due to its cryptic life. However recent phylogenetic studies suggest that Sri Lankan population evolutionary has different lineage from European population.

Quite a find indeed !!!

English name: Sri Lanka Spiny Mouse

Sinhala name: Sri Lanka katu meeya; Podi meeya

Tamil name: Sund’ elli

Threatened status: Critically Endangered (CR) according to Red List of Threatened fauna and Flora of Sri Lanka, 2007

A small mouse with spiny dorsal fur intermixed with short fine hair. It differs from its close relative Mus mayori from having relatively large eyes and ears. M. fernandoni is grayish brown on its back and pure white underneath. The length of the tail (56-78mm) is shorter than the total length of the head and body (90-101mm).  

The species name honour’ the late Mr. H. F. Fernando, the taxidermist of the National Museum Colombo, person who first discovered this endemic mouse  from Kubalgamuwa in Mulhalkelle, Central Province in 1931. , Thereafter it  has been recorded from Kumana (Eastern Province),  Galge  (Uva Province), Butawa and Yala (Southern Province). This nocturnal and forest loving species can be found in tropical rain forests, dry mixed evergreen forests, and among shrub vegetations.

Its lifestyle and ecology have not been not fully understood yet and habitat destruction is believed to be a major threat.
