Ancient civilizations would often tattoo themselves with their totem animal in an attempt to possess that animal's qualities and traits. This very idea can be applied to modern-day tattooing. Choose an animal that has qualities you admire; you might choose a bear for it's strength or a mouse for it's attention to detail. This is a personal choice that can only be made by you.
Animal portraits are often used to commemorate a family pet or favorite animal. Many people consider family pets to be more than just a pet; instead, they too are a member of the family. However, an animal portrait does not have to be of a pet, it could be of an animal with an element of beauty about it's appearance.
It can be easy to forget that wildlife encompasses not only animal life but plant life as well. Use a wildflower, such as a daisy, in your design to make your tattoo stand out. Wildflowers can hold all the beauty of other flowers but with a more interesting, and often more personal meaning.
In 1782 the bald eagle was chosen as the emblem of the United States of America. It was selected as a symbol of long life, strength and majesty. If you are patriotic then the bald eagle could be the perfect wildlife tattoo for you. It has a distinct appearance and can be easily distinguished from other species of bird.
