Family

In Tetrian culture, a family refers to a group of organisms that cohabitate and have close interpersonal relationships. It is common for families to be composed primarily of individuals that are biologically related, though this is not always the case. Traditionally each family shares a unique surname. Families often have their own unique traditions and customs that may date back many generations.

Mating Practices
When two individuals become a mated pair, they have the option of becoming a new family in which case they may choose a unique surname, or one mate may join the family of the other, adopting the surname of the family they have joined.
