Just to muddy the waters further (which is hardly possible ) Jonathon Kingdon only uses the name sengi for the smaller species (such as the small-eared elephant shrew), rather than their bigger relatives like this new one. Maybe we should stick to the Latin and Greek Alan
sengi is a Bantu name (Bantu of course is a pretty broad term), but I don't know what it actually means.
Slightly off topic but also a new discovery...really made me laugh DO NOT do this if you are offended by bad language Google: daily mash giant rat Mods feel free to remove if you think it's not suitable
