Nile crocodile zebras and blue wildebeests ("Connochaetes taurinus"), picking off hundreds of these large ungulates annually. 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.

Equus lambei horse, not an ass. The closest resemblance to "E." "lambei" is shown by the Mongolian horse, "E. caballus przewalskii", now believed to be extinct in the wild. In size and proportions, "E. lambei" resembles "E. caballus przewalskii". Among living horses, perhaps the Yukon horse most closely resembles the Przewalski's horse ("Equus caballus przewalskii") from Mongolia . The upper foot bones (metapodials) of "Equus lambei" are slender compared to Przewalski's horse. The bones of "E. lambei" also closely resemble the proximal phalanges of "E. caballus lenensis", an extinct species from the late Pleistocene of Siberia . Along with steppe bison ("Bison
