Elliot's short-tailed shrew was originally described as a subspecies of Blarina brevicauda, and was only identified as a separate species in 1981. Genetic analysis to determine its precise relationship to other members of the genus has been ambiguous, with some studies placing it as the closest relative to the southern short-tailed shrew, [ 6 ...

Soricidin is a paralytic oligopeptide found in the venomous saliva of the northern short-tailed shrew (Blarina brevicauda); [1] in the wild, shrews use it to paralyze their prey (typically insects). [2] Its name is a reference to "Soricidae", the family to which shrews belong. [3]
