Clans

Those who are unable or choose not to get a bloodline have a chance to instead join a clan

Examples of these clans include;

Akamichi (Tend to have first names starting with Chou) (A possible side job for them could be working in some kind of restaurant)

Nara (Tend to have names starting with Shika) (A known side profession of the Nara clan is to watch over Deer, who's antlers are sometimes used in medicines)

Yamanaka (Tend to have names with Ino in them) (A known ability of the Yamanaka clan is their knowledge of plants, therefore allowing them to open up a flower shop)

Inuzuka (Tend to have names relating to dogs) (Member's of Kiba's family often are veterinarians on the side of their jobs as ninja, specializing in dogs)

Aburame (Known members have Shi- in the begining of their names) (They are masters of espionage because of their ability to communicate with bugs)

The reason these clans' skills are not labled as Kekkei Genkai is because of the fact that these skills are merely taught to the younger generation. (Or in the case of the Aburame clan; being offered to the insects at birth)
