All domesticated ungulates and pet animals will on occasion be hunted by Nile crocodiles, up to the size of dromedary camels ("Camelus dromedarius") and cattle ("Bos taurus") In Tanzania, up to 54 head of cattle may be lost to crocodiles annually, increasing the human-crocodile conflict level. Goats ("Capra aegagrus hircus"), donkeys ("Equus africanus asinus") and dogs ("Canis lupus familiaris") may also rank amongst the most regularly recorded domesticated animals to be taken by Nile crocodiles.

Based on recent examinations of the mtDNA of "Equus lambei" remains, scientists have concluded that "E. lambei" was probably much like the extinct Tarpan, also known as the Eurasian wild horse, and the living Przewalski's Horse. A partial carcass of "Equus lambei" is on display at the Yukon Beringia Interpretive Centre in Whitehorse, Yukon. Evidence from "E. lambei" mtDNA has shown that "Equus lambei" is a close relative
