While elephants' keen memory always gets the spotlight, these researchers have found out that elephants also make great use of their sense of smell!
How? They are able to "sniff out differences in food quantities."
Elephants' ability to make quantity judgement was previously linked to visual cues, as shown in researches which also included dogs, primates, cetaceans, and birds. Now, this new findings are deemed important since elephants' sense of smell is more dominant than their other senses.
Moreover, the implications of the findings may be used in mitigating conflicts between elephants and humans.
