Shrews, which have incredibly fast metabolisms and voracious appetites, feed mainly on insects and insect larvae, making them valuable species in agricultural areas (3). Like some other species in this genus, it is likely that the Egyptian pygmy shrew lives a largely solitary life and maintains a territory (3).
Musk shrews (Crocidura species) typically have litters of between one and ten young, each weighing around one gram. Born hairless, the young are generally fully haired by 16 days of age, open their eyes at 13 days and are weaned by 20 days (3) (6). Crocidura species display ‘caravanning’ behaviour; if the nest is disturbed the female will lead her young to another site, with the young following the female in a line, each using their teeth to hold the back end of the one in front (3) (7). Musk shrews are usually sexually mature by two to three months (3), and typically live to 12 to 18 months of age (2).
