In Akan symbolism there is a design of crossed crocodiles, two joined crocodiles that share the same stomach. You can find the description at the Akan Cultural Symbols Project by scrolling down the page of Akan Political Beliefs. I have always been particularly fond of this as a symbol for the competing interests of constituents in a democracy.
FUNTUMFUNAFU DENKYEM FUNAFU – JOINED CROCODILES
Symbol of UNITY IN DIVERSITY, DEMOCRACY, and UNITY OF PURPOSE
The symbol is also referred to as odenkyem mmemu – Siamese twin crocodiles joined at the stomach. From the proverb: Funtumfunafu, denkyemmfunafu, won afuru bomu nso wodidi a na worefom efiri se aduane ne de ye di no mene twitwi mu. Literal translation: Two headed crocodiles fight over food that goes to a common stomach because each relishes the food in its throat. This symbol stresses the oneness of humanity in spite of cultural diversity. It also emphasizes the need for unity in the family or state. Members should not quarrel or fight for selfish interests, for what each gains is for the benefit of all. It also emphasizes the reality of individuality in relation to one’s membership in a society. Much as the community interests are to be pursued for the common good, individual rights, interests, passions and responsibilities cannot and must not be trampled on.
This symbol, in essence, depicts the Akan notions about the inherent difficulties of reconciling individual and group interests in a democratic system.
