Elephantiasis is caused by obstruction of the lymphatic system, which results in the accumulation of a fluid called lymph in the affected areas. Functioning as part of the immune system, the lymphatic system helps to protect the body against infection and disease.
African elephants live on the savannas of Africa. There are two species of elephants in Africa; the savanna elephant and the forest elephant, (Loxodonta cyclotis).
