在刚果北方的Ndoki森林进行的一项实地研究中发现了西部低地大猩猩（Gorilla gorilla）的抓土行为。这种行为的目的可能是吃昆虫，尽管昆虫的收获可能相对较少。在粪便样本中发现的昆虫外观的季节性变化与土壤划痕的频率一致。抓土行为被认为对大猩猩的营养贡献不大。
Soil-scratching behaviour by western lowland gorillas (Gorilla gorilla gorilla) was recognized in a field study in the Ndoki forest of northern Congo. The purpose of this behaviour was probably insect eating although the harvest of insects was likely to be relatively poor. The seasonal variation in the appearance of insects found in faecal samples coincided with the frequency of soil-scratching traces. Soil-scratching behaviour was considered not to make a large nutritional contribution for gorillas.
