i.Increase in count: The discovery has increased the number of White-toothed shrew (genus Crocidura) species in India from 11 to 12 and also increased the mammals count from 429 to 430.
ii.After 43 years: The current discovery of new insectivorous mammals was held after 43 years of ZSI’s discovery of Crocidura Jenkinsi on the South Andaman Island in 1978. This discovery is based on osteological and DNA molecular studies of the specimen.
