Food phylogeny

 

Following the recent paper in the Journal of Zoo and Aquarium Research describing food-washing behaviour in babirusa (Ito et al., 2017), it seemed to be a good time to look at the phylogenetic aspect of this behaviour.

The food-washing behaviours of primates (Maca spp., Pongo abeliiGorilla gorilla and Pan spp.) are well known and observed both in the wild and in captivity.

However, more research is needed into the food-washing behaviour of the babirusa pig (Babyrousa celebensis) and the raccoon (Procyon lotor).
